Hello Mark: Installing diodes can cause severe problems with nearby broadcast stations.
During the summer months and lightning months I remove my preamps from the antenna elements to protect them. I am now just getting them installed tomorrow morning to prepare for the Fall Stew contest on Saturday. Be careful making modifications that may hurt your array performance 73 Tim K3LR -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Mark Robinson Sent: Thursday, October 17, 2019 8:54 PM To: [email protected] Subject: Topband: Hardening the 8 Circle Receiving Array I have the DX Engineering 8 circle receiving array sized for 80/160m . It has been a fantastic performer but I have suffered damage to the active antenna amplifiers on two separate occasions due to nearby lightning strikes. I am looking at a way to protect these amplifiers. I was wondering if I can add a pair or dual series pair (4 diodes in total) of back to back diodes - say 1N3600, across the input to ground terminals on each amplifier. Will this affect the performance of the array in any way ? 73 Mark N1UK _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
