[TowerTalk] Bias Tee & Lightning Protection

[Art Greenberg]

I'm considering adding a mast-mounted LNA for 2m and I want to deliver 
12V to it through the coax. Currently, all of the lightning arrestors in 
my entrance panel are DC blocking type.

I can see a couple of ways to accomplish this.

- Replace the lightning arrestor for the 2m antenna with a model that 
passes DC.

- Install a bias tee on the antenna side of the lightning arrestor and 
run the 12 supply to it through a "control line" type arrestor.

Your thoughts?

Thanks.
