Hello Amps,
Thursday, April 8, 2021
I agree entirely, I am active on LF at 137kHz and had a whale of a time
tracking down an SWR issue. it turned out two UHF connectors didn't like a
kilowatt of LF through them. I spent ages on it until I used my AIM4170
analyser to do a TDR and it showed exactly where the issues were. I am now
slowly changing out all UHF Chinese junk to branded N types and have had no
issues with them, save damage to my wallet and time...
I guess the old adage "you get what you pay for" is evident in my case.
Best regards,
