Hi to all.
I'm Pavel Milanes, CO7WT, from Cuba, member of the GROS.
I have a question in my head and I have not enough arguments to decide, I have to BUILD my own antennas, so having this into account:
What is the most cost effective (cost / gain / difficult in building / omni pattern) that can I build?
I have in plans to build a LNA from a servian pdf using the BF998 MOSFET, that will be at the antenna point, Andrew Heliax LDF-4 50 ohms for the download to the shack and of course this is a FIXED antenna, with NO rotors.
I have heard of and modeled all this ones and all have his pros and cons... - QFH - Turnstile dipoles - Turnstile moxons (100 ohms) - Eggbeater
I think (correct me if I'm wrong) that the best election will be the QFH, because his really omni pattern, beside the fact that I will have to build two of them (rhcp and lhcp switched properly with a relay) and the lower gain will be 'compensated' with the LNA...
Please, I don't want to start a flag war, only heard about some experiences to decide my self.
Last tip, TRX on 70 cm will be a Kenwood channelized TK-382N for FM (5W) and TRX on 2m will be a Alinco DR-130.
