I have been using GMRS for my personel busness for a long time It is only myself and the wife, Most of the comm between us is passing info from the house to the workshop.

I don't know the exact distance, but I do know that RJ45 cable can effectively pass signals/information approximately 150ft without a repeater. Whether or not the radio pushes enough power to go that far and the head unit can pick it up are two different stories. I wish I could have stayed longer as well. Without the ground on that extension cord and your antenna/radio not being grounded, that could have been causing the SWR we saw. I would check all connections, remove moisture, make sure you don't have any shorts in the ground on your LMR400 (not grounded to the shielding by accident), and try hooking the baofeng to the antenna line through the SWR meter bypassing the duplexer. If the issue goes away then your duplexer is not tuned right, if the issue remains then you have an issue with your cabling/antenna. Easy way to rule out the duplexer.
