A friend had an issue also and he said the phasing cable were marked wrong. Not sure if that is your issue.

Hello All, I recently assembled and mounted M2 LEO-Pack antenna system. Problem: The 2 meter SWR was impacted significantly "after" the antenna was mounted to the boom and phasing lines, coax, and peripheral wiring was secured. (The 70 centimeter side was not impacted.) I'm confident that adjustments to the shorting bars will bring the antenna back into resonance. Question: What's the best way to make the adjustments and perform the tests? Obviously I have both horizontal and vertical entities to adjust. Is there a sequence that I should follow? Any input is greatly appreciated. Warm wishes for a safe and healthy holiday season. Kind Regards best 73sMark Morris N3NJ

Just talked to him and he said that when got the phasing cable right the SWR was flat across the band. So hopefully that is your issue too. Jim, W0NBC.

Thank you Jim. The antenna tested fine (initially) with all of the phasing lines connected. The issue didn't present itself until the antenna was mounted to the boom and everything was secured (wire ties etc).Kind Regards, Mark Morris -------- Original message --------From: Jim_WØNBC [email protected] Date: 12/27/22 12:22 PM (GMT-05:00) To: markemorris [email protected], [email protected] Cc: [email protected] Subject: Re: [AMSAT-BB] Leo Pack issue Just talked to him and he said that when got the phasing cable right the SWR was flat across the band.
