at $110 for a single Tohtsu 3500, is that really a cost saving for this
kind of outdoor switching?
Just did a quick look, because my remembering of this is that most
people who try to do a cheaper homebrew come to appreciate the different
issues in making something that works well?
comparison:
ICE has (thru array solutions)
http://www.iceradioproducts.com/rfswitch.html#3
which claims:
"standard rating 7,500 Watts PEP / ICS, insulation rating of poles and
relay armatures 2000VAC, switching time 11ms., usable up to 500 feet
from feed voltage source, 50 / 75 ohms, 0.1 db insertion loss, DC-30 MHz
... each switching unit contains a resistive heating element which may
be switched on and off from the control source or left on 24 hours per
day (total cost about 5-7cents per year), keeping the relays and chassis
housing warm and dry -- even in harsh environments. All models rated for
indoor / outdoor service"
2:1 for $58 or $62
6:1 for $208
9:1 for $228
$30 for a second pvc case for secondary protection of the connectors etc.
