Remote Antenna Switch
For many years I have been using an Ameritron remote antenna switch, model RCS-8V, to select among my dipole antennas. Lately it has become erratic and some of the ports no longer work. Looking to replace it, I found that good remote switches are somewhat expensive. I thought I could build my own, but the problem was finding a suitable waterproof enclosure.
One day I was browsing the interesting Adafruit web site, and I stumbled across a waterproof plastic box approximately 17x12x7.5 CM. I ordered one and here is the result. (I haven't provided a link because the box may no longer be available.) (Also available from Banggood.)
The relays are 110VAC, because I had 4 of them in my parts box. No reason why other voltage relays could not be used, just provide the correct voltage for your relays. I used the dead bug wiring method; simple but only good for HF. BTW my relays are DPDT and I wired the two sides together, which should provide longer life and lower contact resistance.
