¿ªÔÆÌåÓýCongradulations, it looks great! I like your method
of non - soldering the cables, unfortunately, it would not last long around here
where I live by the seaside, I sprayed clear protective lacquer onto my polished
copper loop but it is still managing to corrode in spots, I presume you are
living far inland away from any salt spray?
Great photos anyway and I enjoyed
looking!
Best regards!

Ditto! In 6 weeks you will have enough oxidation built up around
those joints that the transmit efficiency will drop like a stone. Connection resistance on transmitting loops needs to be held to an absolute minimum. There's a lot of current flowing at the feedpoints and very high voltages _with_ high currents at the capacitor. Best if you can solder these joints and then insulate them from the weather. 73, 'Bear' NH7SR --- In loopantennas@..., "Michael Stevenson" <portstevos@t...> wrote: Congradulations, it looks great!
