Finally, the sun stayed out long enough to do stuff outside. One of the things I wanted to try was setting up the multi-feed for my 1.2m CM dish in hope of recreating it.
The goal is to create a multi-feed arrangement for 1w and 5e. These are generally borderline here on anything less than 1m and 1.2m gives 24/7 reception with decent rain margin on both (except SES-5).
The primary focus is 1w, so aligned the dish on that first...
14.5dB - not bad, considering my 1.8m gets 17dB on the same transponder...
5E was 12.5dB (no picture).
After a LOT of faffing, these are the maximum signals I could get in multi-feed setup.
1W (shown as 3E on meter) and 5E respectively...
And here's how it looks.
Err... frankly, I think it's a pretty awful design. The one for Gibertinis is much more solid - this is nothing short of a glorified meccano set. But... it works.
Only a temporary lash-up - as soon as the wife saw it, she shouted "YOU DON'T NEED ANOTHER DISH!". Partially because I am deaf and partially because we already have three dishes around the property...
I can take measurements for anyone interested.
