R: [TowerTalk] Best antenna switch ?

[Gian Luca Cazzola]

Zoli,
if you really need the best coax switch on the market I think it should be a
BIRD ELECTRONICS, for example BIRD 74
(6x1 - N connectors).
It is the only that commutate a coax line including the N sockets ( with the
higher insulation port to port - more than 80db from 0 up to 2 or 3 Ghz).
The only problem is the very high price new (I think more than 500-600 US$ -
ask www.rfparts.com ).
You can find it also used at a much lower price.
