Rev B of the TinyGawant antenna has arrived! New features include a switch for operating between 20-10m and 40-30m, and an integrated SWR indicator. Initial results showed it tunes across all bands (yay!), but the SWR meter didn’t work on the first try. After probing the LED, I discovery that I had installed a Zener diode instead of a Schottky diode across the bridge! After replacing it with the correct part, the SWR light worked as expected!
Next up: Field Test!
