I did quite lot of research about protective limiters. The best solution found
is to use the special TVS diodes RClamp2502L by Semtech which incorporate surge
rated, low capacitance steering diodes and a TVS diode in a single package

Array Solutions no longer handles the K9AY components, which actually
came from K9RU's Wolf RF Systems. It looks like the ICE limiter is
still out there, and reasonably priced
It's likely you won't need any protection from the transmitter
(lightning protection may be another story). To verify this you can
either use an oscilloscope on the output of the K9AY or just build a
diode / cap detector and use a voltmeter.. Then ramp up the power to
see how much voltage is
When I owned my P40A station I had a Pennant very close to my 160m TX
vertical. A K9AY preamp was at the RX antenna feedpoint with voltage
fed though the coax. If I recall correctly I only shorted the RX line
going to the radio during TX and left the preamp running. Most of my
operation

I'm in the process of building up a K9AY loop, using the Array Solutions
boxes, and it occurred to me that
or my K9AY
Loop. I think I got it from DX Eng ~ 10 yrs ago, but also chk w/ Array
Solutions since I think they now handle the K9AY Loop. - Alan K9MBQ

I'm in the process of building up a K9AY loop, using the Array Solutions
boxes, and it occurred to me that I probably need to work out some way
to protect the preamp in the shack-end box from transmitted RF,
particularly since the K9AY loop is only about 60 feet from the vertical
leg of my
11 matches
