ive just ordered a triax 88cm solid to replace my 80cm mesh and am wondering if ive done right as im on chimney also. the mesh dish if obviously better against the wind. ive upgraded size mainly for fox turk, but wonder whether a solid is right for up there. 8ocm has been no problem for many years

Don't councils impose a limit of 45cm for dishes mounted on a chimney stack ?

If the dish is being installed on a chimney stack, it should not exceed 45cm in size, and no higher than the highest part of the stack.

I just did a google search for my post above and the first 4 councils that came up all said 45cm limit.

Dwellings & Buildings under 15 metres in height

Planning permission is not needed provided that…

there will be no more than two antennas on the property overall;
if you are installing a single antenna, it should not be more than 100cm in any linear dimension;
if two antennas are being installed, one is not more than 100cm in any linear dimension, and the other is not more than 60cm in any linear dimension;
the cubic capacity (volume) of the individual antenna is not more than 35 litres;
an antenna on a chimney stack is not more than 60cm in any linear dimension; and an antenna mounted on the roof only sticks out above the roof when there is a chimney-stack. In this case, the antenna should not project more than 60cm above the highest part of the roof, or above the highest part of the chimney stack, whichever is lower;
Dwellings & Buildings under 15 metres in height in Conservation Areas
Planning permission is not needed provided that...

The above six bullet points are met; and

an antenna is not installed on a chimney, wall, or a roof slope which faces onto, and is visible from, a road.
Dwellings & Buildings over 15 metres in height

Planning permission is not needed provided that…

there will be no more than four antennas on the building overall;
the size of any antenna is not more than 130cm in any linear dimension;
the cubic capacity (volume) of each individual antenna is not more than 35 litres;
an antenna fitted onto a chimney stack is not more than 60cm in any linear dimension;
and an antenna mounted on the roof does not stick out above the roof more than 300cm above the highest part of the roof.



Dwellings & Buildings over 15 metres in height in Conservation Areas

Planning permission is not needed provided that…

The above five bullet points are met; and

an antenna is not installed on a chimney, wall, or a roof slope which faces onto, and is visible from a road.
Flats

The law is framed to discourage the occupiers of flats from installing individual dishes. A dish on most flats will need planning permission unless it is the first or second dish on the building as a whole. This is intended to prevent blocks of flats from becoming disfigured by "rashes" of satellite dishes. It may be possible to use shared antenna systems without the need for each household to install an individual antenna.

Shared antenna systems might be worth considering if:

landlords or owners have banned individual antennas;
a shared system would be more environmentally friendly than for each home to have its own antenna; and if
planning permission is unlikely to be granted for several antennas on a single building
Submitting a Planning Application

Your application should be submitted on the standard planning application forms. You will also have to supply four copies of a drawing showing clearly where on the building the dish will be located.

A fee is payable when the application is submitted. The fee is not returnable if the application is refused. However, there is a right of appeal (at no cost) to the Office of the Deputy Prime Minister against a refusal, and a "follow-up" application to the Council is free if it is submitted within one year of the refusal of the first application.

Application forms and fee details are available from the Planning Service.

Listed Building Consent

Whether or not planning permission is needed for your satellite dish you will need Listed Building Consent if the property is a listed building. Special application forms are available, and you should also submit plans showing exactly where on the building you wish to install the dish. No fee is payable for this application. If you are not sure whether your house is listed, please ask the Planning and Transportation Service for advice.

Council Tenants

If you are a Council tenant, you should apply for permission to install a satellite dish via your local Neighbourhood Management Service office. The telephone number is inside your rent card. This applies whether or not you need planning permission for the dish, and is separate from Planning Control, which is dealt with by the Planning and Transportation Service.

If having read this leaflet, you are still unsure as to whether you need planning permission for the installation of a satellite dish, please contact the Planning Department on the address below. In addition, we can provide you with a leaflet produced by Central Government on this same issue.

If you ask the council whether you need planning permission for your dish and you intend to install one over 60cms, I can't imagine them saying that you do need PP, but not to bother! By asking, you commit yourself. If the dish won't be too conspicuous, and you get on well with your neighbours, consider mentioning it to them, then just going ahead. Planning officers don't go round measuring dishes on chimneys routinely (although some would if they could)! The worst that can possibly happen is that it has to come down - eventually! If it remains there for 4 yrs., you have got away with it!

:eek: I would be very wary of mounting anything on a chimney stack - the wind loadings on a large dish can be quite considerable. Before getting it done you should have the chimney surveyed to check for structural soundness and mount the dish as low on the chimney as is practical. I wouldn't consider it unless the chimney is at least 2' square!;)

I agree with that.

With the extreme and unpredictable weather we now seem to get in the UK, it is no longer safe to assume 'it will be ok'.

my chimmney stack size is over 2 ft wide as it is the old terraced house type , the stonework has recently been repointed & is in good condition so if i mount my dish low then should be fine , i am looking at a 90cm would that be ok???

i like mine on the ground, it hasn't got far to fall then, if it does fall over.

plus the sat signal has just gone 72000 kilomteres, so whats another 20 feet! lol

unless you dont have line of sight to the sats you want of course.

I would think those big dishes are asking for trouble on a chimney stack , judging by the wind pressure problems I had with my triax v1.1 metre dish on a stainless steel pole bolted to my wall ( and not bolted to a chimey stack , as you should not drill into them but should use a lashing kit ) , and its now on a scaffold pole , anchored in 2 places to my house wall and rock solid ( with a new motor )

if you look here

https://www.satpimps.co.uk/showthread.php?t=60102

you will see single dish options for the main eastern sats that allow 4 or 5 lnb,s on a zone 2 sly dish , and there is no reason why you cannot use an 8 way diseqc switch and run a motor to one of the inputs , and have the rest going to the single dish lnb,s , and set this up in the diseqc option in your receiver

I have a 5 year old samsung that can drive a motor from a diseqc switch input , and have had other lnb,s connected to the other inputs

so my advice is leave one at the back doing say 1 west to 45w and have a single 60cm zone 2 dish on the stack or house front doing the main eastern sats

its definitely 1 option that you should consider , depending on how many of the eastern sats you want

and dont forget that 60cm is the maximum allowed on a chimney stack ( so a zone 2 dish is 59cm )

As stated above, a lashing kit (in fact 2 heavy duty kits spaced well apart for stability) would be necessary. A mesh dish might be adviseable, but you may not find one above 80cms. If you do have to use any bolts they must go into the stonework not the mortar. One bolt tightened ito the mortar can produce a hairline crack all the way round!

you've not told us how big is your chimney stack
Ive got a 1 m dish in mine but my chimney is about
5 ft high
front to back about 3 ft
side to side about 8 ft
one of the 8 ft sides is facing due south so the chimney acts as a wind barrier had a motorized dish there for about 22 years
never had any problems yet


you only need planning permission for any size dish on a chimney if any part of it sticks up above the apex of the roof

so providing your dish is 1 m or less and none of it is above the apex of the roof you don't need planing permission well thats in Nottingham anyway


you will need planing permission for a zone 1 sky dish on a chimney if any part is sticking above the apex of the roof

my chimmney size is about the same , have you got a mesh dish or solid? as mesh would be best for strong winds

Hello,

Due to some high trees and my neighbours house it is looking like I will have to mount my dish on my chimney.


Due to this I am looking to use an 80cm Mesh dish. And 2 heavy duty lashing kits.


Can I also mount a motor on the lashing kit? And is there any kits people on here recomend?

I live in the North of Scotland, and have had an 800mm solid dish on a chimney for many years, without any problems.

i would never reccomend a dish installation on a chimney. Ive seen some shocking pictures recently where dishes have brought down chimney stacks, the last one locally in the gales last week where it ripped out of the chimney stack and brought most of the stack down through the house! This was an 80cm dish.

Ive always said, the lower the better, especially for motorised set ups.
Easy to install
Easy to maintain
Less weather/wind interfearence
doesnt look unsightly on the side of house.

My 1.1m dish is in the back south facing garden wall 1 m off the ground and i can get 42east-40west no problem! My mate the other day who has his 1m dish on the roof was moaning cos he could even get a lock on 28east as his dish was wobbling like a jelly, i sat there watching MBC on 26east with no problems (Very weak signal here this far west/north) and the wind was gusting 120km/h

A mate had a 80cm on his chimney.
In the gales a few years ago it came down causing loads of damage and his insurance company refused to pay out, he went legal and still lost.
He lost as the chimmney had not been designed to carry such a large dish, and this was proven when the wind brought it down. Also as he had not declared it to his insurer as it was a risk increase.

Hi Guys
Be very carefull about fitting dishes of any size on chimnys have the chimney checked out first by a reputable builder it may look perfectlly ok to the eye as mine did till i had it checked out and found that the morter was like sand due to the weather we have in the u/k i had it completely rebuilt, afterwoods decided to mount dish at the bottom of garden for safety reasons

As a diy job you can get up on the roof and do whatever you think best.....

However a proper installer would no doubt make the sign of the cross, make his excuses and leave.

Don't forget a chimney is nearly always just one course of bricks or blocks and therefore not very strong. A friend of mine who works for Sky says
that they are not allowed to mount dishes on chimneys and he fits only the
tiny (by our standard) dishes.

I've had an 80cm mesh dish now up on a high chimney (50+') for at least 12 years - never realised it was 'illegal'. Co. that put it up never said 'owt (NW Satellites? Chorley - now long gone) - steel bands around substantial chimney.

As I understand it on time its been up - council now cannot do 'owt about it anyway

it not illegal to mount a satellite dish on a chimmney stack
and you only need planning permition if any part of the dish sticks up higher than the apex of the roof ( thats the highest point of the roof )
actualy you need planning permition if your tv aerial is higher tham 1.65 m about the top of the roof so there for about 90 % of us are breaking the law as most aerial fitter use a 6 foot mast near the top of the chimmney stack so even if the aerial mast at the bottom was touching the top of the roof it would still be to high than what is leagal

1)No decent installer would consider fitting a dish this size to the chimney.
2)Your insurance would be null and void.Just imagine a gale brings the dish or chimney down,and kills,or seriously injures somebody.You would be open for all sorts of claims and criminal prosecution.

Thanks Guys, Just the info I was looking for. This thread is worth a bump if not a sticky. Looks like its a garden install for me. Which leads to the next question. What's the longest cable lenght recommended between a motorised dish (1.2m) and the receiver?

if a old house its prob held together with black mortar and repointing it is not going to make it a lot stronger when you bolt a dish upto it.

A very late bump for this thread!

Unless your really cannot because of the required "angle of view" (both height, and E-W range) install the dish at ground level - it's easier, cheaper and quicker.

Just mount a steel pole (scaffolding poles are good, but concrete them firmly) into the ground and make sure they are absolutely vertical. Then fix your chosen dish mount (fixed or steerable) to the pole and do the final alignment. Then, and thereafter, alignment is quite easy - and dead easy If all you want is 28E - and any fault-fixing is relatively quick/cheap/easy. I initially installed my steerable dish on top of my house front bay window (very difficult/dangerous!) - but now it has been/will be on a 2m high pole in the back garden, and that means that installation /adjustment/ fixing is relatively easy/quick (no ladder, just a small pair of kitchen steps!).

And my chimneys are totally unaffected and safe ( hope the builders did a good job nearly 100 yrs ago, and they seem to have done that :-))!

Hi
For many years I had meter dish on a 5 ft pole at the bottom of the garden. It picked all sats up. I had 80ft cable which I put in plastic tubing and put just below grass surface.The pole was screwed to a paving flag which I set in cement so it was level.Good luck.Better and safer on the ground and easey for repairs :)
