Last night before bed I decided to use the double male and double female connectors I already had so I cleaned every connection with alcohol and applied dielectric grease to every application and tightened them well. Then I hooked it to my Q6 Pro after cleaning & greasing that connector and was amazed at the SWR. Almost a flat-liner on every channel. So now I can't wait for the DX to get rolling.If everything is done right with the antenna installation there shouldn't be any change to SWR, especially with such a small extension. As a general rule in a base station setup, if changing the length of any coax changes the SWR significantly, then there are other problems with the antenna or coax. SWR should NOT change when coax length changes.
