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)

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 ?
