R: AO51 Signals



Hi Andrew,

to receive AO-51 I have
38 elements cross yagi, left and 
right polarization,
SP 7000 pre-amp and 30 meters RT 50-20 coaxial 
cable.

At 30° elevation the downlink signal is  S 9+30 into my old 
Kenwood TS 790
if I swich off the pre-amp the signal drop down at S 5-6
(my opinion and experience is the pre-amp is very important)

73"

Hello

I built a 10 turn helix for 435 
MHz.

I have 15 meters of RG-213.

Radio is an ICOM 706 mkii G

I am 
not getting strong signals like I would have expected ?

Can someone 
share their setups and signal strengths ?

Maybe a pre-amp might help ?

Am I getting too much loss in the cable ?
