Bonding everything (all grounds) to the main A.C. grounding electrode in accordance with the National Electrical Code avoids voltage differential during strike events. (at least that seems to be my e
So if the SWR returns to normal with a towel, what would a gentle shaking of the antenna using the rotor to rock the antenna back and forth do? I'm sure some of those rain drops would drop.... 73 ES
For a band decoder, I used the UM BCD-10 (now BCD-14), (see http://www.unifiedmicro.com/BCD_14_MAN.pdf). Very easy to configure using DXLabs, Commander, Configuration, and a device table to output a

I've used a Butternut HF-2V, 40 - 80 vertical which is NOT trapped but uses capacitance to work around the adjustable 80 meter inductance. In my installation I've used "umbrella" top loading with fou
