Don’t work with cell freqs. My expertise is in receiving HF systems and antenna distribution networks.
To me a 3rd order intermod (OPIP)is great if it’s above 80!..........
I understand, but you have to realize exactly how much dropped calls and interference means to the cell industry. We are talking near a trillion a year in call costs and revenue. These effers are serious about it.
I once got paid an assload to go to their number one cell site at about 3AM to help them take down and test some new antennas. It was in Reston, VA, BTW.
They had three crane crews there to catch each side of the triad tier and install the new antennas. Also had a host of mobile crews cruising the ‘cell’ to gauge performance. It was a screaming expensive operation. Finished by 4 AM and back on the air making a buttload of money.
