I can’t hardly believe that because when I got my 1/2 wave and it solved my issues, I called ER and told them the situation. She ( don’t remember her name) said “oh yeah, the 1/2 wave works much better for your application). Tell them your sending the 1/4 wave back and want the 1/2 wave as an even exchange. I can’t believe the inconsistent technical advice coming out of their shop!
The 1/4 wave can NEVER be as good as a 1/2 wave unless the 1/2 is installed wrong!
With that said it’s almost always an issue with the installation. Regardless of antenna, re-route the electrical and the coax (by the way the cheap coax they send really is not very good, it leaks signal which is what messes with the vehicle electronics) the thicker the coax the better). But that’s a whole new lesson/education. Route the coax and power cable opposite side of any electronics, stay as far away from the ECM as possible, make sure everything is grounded (radio, antenna, coax, etc.)
These things are great when everything is right, it doesn’t take much for them to be wrong.
And as for range yes they should get a mile per watt in ideal conditions, with trees, hills, etc. assume 1/2 that at best. The best handheld is 8-10 watts, the ones most of you guys are using are anywhere from a 1/2 to 5 watts at most (nothing wrong with hand helds just talking about performance). Rugged mobile dash mount is as high as 60 depending on your model or 25 with the cheapest model. A handheld on top of a hill will out talk a dash mount trying to transmit through obstacles. In theory the more power, the better the antenna the better the performance.
