Hello all, I hope I’ve posted this question in the correct area. I’m running a Stryker 447hpc2 set at 1 watt dead key, Stryker SR-a10 single antenna thru rg8X coax. My SWR was at 1.2. A few weeks ago I added a new 2 pill amp with 9’ of 8X coax jumper. With the amp connected but OFF (meter between radio and amp) I key mike and still show 1.2 SWR. I turn amp ON and key mike it will jump to 3.8 SWR. So I’ve never used the amp since I installed it. All power leads are connected directly to battery with additional ground straps on each component chassis My question is I’m not sure what to do or try to lower the SWR so I can use this setup?
