Reading the AO-51 book by Gould where he discuses the L band requirements. For occasional contact 150 W EIRP is needed. For superior performance 1 Kw EIRP needed. Assuming I start out with 10W to a 16 turn helix 40 feet away. Guesstimating- 5-8 W at the antenna, helix gain 8-12db. Guestimated EIRP about 40W (worst case). Am I figuring this correct? If so then AO-51 is performing better than what the book says. I am trying to "fine tune" what I have.
