I have a 38cm aluminium dish that I use for my caravanette and european holidays, it works fine with a single lnb but I decided to fit a 6 degree monoblock to make it a astra 1 / hotbird setup.

After fitting the lnb and lining the dish up on hotbird , astra 1 would not clear and neither would hotbird when I lined up on astra 1.

It soon became obvious that the feed arm was too short on this small dish and the lnb was designed to work at 6 degrees at abot 18" to two feet distance from the dish.

As the feed arm is only 12" long I guessed that this was only half the distance it should be on a normal set up, this would give a separation of only 3 degrees at this distance for astra 1 and hotbird which is normaly 6 degrees.

I then tried a 3 degree monoblock on the 38cm dish and bingo, both now work perfectly.

Anyone thats got a portable dish might find this usefull. :respect-048:

just to say I mentioned something similar to this in the sticky thread regarding 59cm zone 2 dishes and the arm on those had to be extended for use with a 6 degree monoblock lnb so I have no doubt it applies to any size dish

If you put a 6 degree Monoblock LNB on a zone 2 it does 9 degrees 19 and 28 east have fitted a few 6 degree monoblocks only do 6 degrees on 80-85cm dishes

I currently use a sky zone2 (60cm) dish to receive astra1 and a second dish for receiving astra2, both connected over a diseqc switch. It would be great if I could get rid of the second dish and have both on one dish.

I live in South London and was wondering if I would have any troubles with this setup.

Thanks.

I put a 3 degree monoblock on a 38cm minidish and because of the shortness of the feed arm, it acted as a 6 degree monoblock and picked up 19e and 13e.

It was meant as satpaul says for a 80cm dish, the 38cm had its uses for hols etc.
