Hello:

Anyone have any strong opinions regarding PolyPhaser, ICE, and Alpha Delta
Lightning Arresters ?

Would be for a receive only antenna.

Do I want the dc blocked variety, or doesn't it matter for receive only (0.5
to 30 MHz) ?

Thanks,
Bob


Polyphaser is the best in the industry, bar none. I've used them and
have nothing but high praise for them.

ICE has a pretty good reputation as well.

I don't know if A-D still makes it, but at one time they had a design
out there that would actually INCREASE the amount of damage a strike
or induced EMF from a nearby strike would cause -- it had a gas tube
tied from center-conductor to ground, but no connection (gas tube or
otherwise) from shield to ground. Basically a "please, kill my
equipment" device.

I know A-D sells other designs, but since they sold that one at all,
I'm wary of them.

The designs I like are all DC blocked gas tubes, but you don't have to
go that way. I know Polyphaser sells some gas tube/semiconductor
versions that will do well on broadband receive as well.
