[TowerTalk] Resistor Across a Choke Balun

[WW3S]

so what is the best way to drain static off a vertical with either a 
resistor or choke?

>After getting my hands on a floating 80m vertical one summer and then getting up off the ground, I decided then and there that the 50K 200W resistor in my junk box could do some good and maybe save me a future surprise.  Ran it that way for a few years until it came down in 85 mph winds once night.  Never got shocked again. I'm more careful now - don't need to learn that lesson more than once...

The MF/HF cookbook is based on more than a year of winding and measuring more than a thousand chokes; the VHF/UHF cookbook is based on Fair-Rite data sheets for specific cores. This material has been in the ARRL Handbook for a while.
