For AO-40 I had 10 watts thru about 8m of LDF450 and 1m of superflex
into a 25 ele loop yagi. I wasn't very happy with it, could only get
in with low squint angles. So I moved to a 1.5m dish with CP patch
feed that was fed with 20m RG58 (yes RG58!), this gave me 1 watt at
the base of the dish. I fed this 1 watt into a 16 watt brick amp and
I became one of the "Big Boys".
For AO-51 I am using the 25 ele loop yagi fed with 8m of RG214 from
24cm icom HT into 16 watt amp. Works well with AO-51, there are many
fades but that is the spacecraft moving around, so I am not to
worried about CP.
