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 transmi
I use a Model 197 RF Limiter/Arrestor by Industrial Comms Engineers for 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
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, but I have no idea wh
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 a
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 th
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
Hello Pete: This is the RX limiter we use to protect front ends at K3LR. https://www.dxengineering.com/parts/dxe-rg5000hd It works very well. 73 Tim K3LR --Original Message-- From: Topband [mailto:to
Severe overload problems in the K9AY array from the transmitter will also cause overheating/burning up the 2 watt terminating resistors in the relay box at the antenna. I've seen arrays that are only
Another solution is the Mini-Circuits Transceiver protection device RLM-33-2W+. Jim - KR9U --Original Message-- From: Topband [mailto:topband-bounces@contesting.com] On Behalf Of Martin Kratoska Sent
I'm on a small lot way to many antennas here. I use the _DXE-RG5000HD and _ _DXE-RG5000HD-PM_. Works great so far 1500 watts on 10 thru 160. Receiving antennas Beverage and K9AY Loop. No testing here
I use these at W5ZN. They are excellent. 73 Joel W5ZN This is the RX limiter we use to protect front ends at K3LR. https://www.dxengineering.com/parts/dxe-rg5000hd It works very well. 73 Tim K3LR --O
