Guest Jim Posted February 13 Report Share Posted February 13 I purchased a mobile antenna and I can’t hit the repeater with it. The swr is 1.27 but I can hit it in my house with the rubber duck all connected to a handheld ? Quote Link to comment Share on other sites More sharing options...

I'm thinking you have some kind of mobile radio installed in the car with the mobile antenna? Or are you using the handheld in the car with the mobile antenna connected?

WRWE456 Posted February 13 Report Share Posted February 13 Hello and welcome! Most mobile antenna's require a ground plane such as the metal of a car body to work properly. If it's a magnet mount you can place it on a cookie sheet or pizza pan which will provide a ground plane. You will get better performance outside the house and as high as you can get it. Same with the handheld. UHF (GMRS) is mainly line of sight. The more stuff the signal has to penetrate the weaker it will be and the shorter your range.

WRWE456 Posted February 13 Report Share Posted February 13 You didn't say if you were using it in a car. I was assuming you were using it in the house. More details will help. Quote Link to comment Share on other sites More sharing options...
WSAQ406 Posted February 29 Report Share Posted February 29 With that SWR I don't think it is the ground plane. Can you give more info? Quote Link to comment Share on other sites More sharing options...
