Re: Low Band Receiving aerials.
David Cutter
There are microwave-rated relays that do a good job of 50 ohms and not really expensive if you are in to VHF+ I don't think these things matter much at HF and MF for receiving. It's not about maximum power transfer theorem it's about signal to noise ratio.

More of an issue if you are a high speed break-in cw operator is relay timing. If it's an issue then a proper sequencer might be needed for use with linear power amplifiers, but some modern rigs have adjustable timing to wait for relay strings to close/open. David G3UNA
