lightning arrestors [RE-wrenches]

[Allan Sindelar]

Funny, I just spoke with Kim at Transtector this morning, first time. A
client had requested DC arrestors with a LED "working OK" indicator, and
Transtector makes them. Great, but she quoted $469 each, list. Aren't
equivalent Polyphaser about $200?
We have long used Delta, but described it to clients as "basic protection,
widely and generally accepted in the RE industry, but not very
sophisticated. Please see a lightning specialist for better, as this is not
our specialty."
