Where I live is in southeast Ohio lots of tree’s and hills . My understanding is that unity gain antenna would be more useful for my area . I’m on a hill my location on that hill puts me at the same level as all the trees . If I raise my antenna to 20 feet that puts the top of the antenna approximately the same level as the tops of the trees in front of me and behind me. I can’t go much higher either. Worst part is 50yards from my house the hill I live on goes just a little higher and you can see clearly for 10 miles or more. Now in the winter I can reach 7 miles one way and 10-12 miles the other way . If that helps what kind of antenna would be best for my location? I guessing the Browning/ Tram 4160 seems to be the one to me that makes the most since. I’m using a mobile antenna with a ground plane. Like I said one way from my home I’m getting out 7miles & 10-12 miles the other way . Thats with a radio that is only putting out 20watts. I had the BTech U25 amp when it was working it put out around 30-35 watts hooked to the same antenna setup , I would be able to reach 12-15 miles in the direction I’m reaching 7 miles now . In the other direction using the amp I was getting the same that I am now . I know why that I only got the the same on 10-12 mile direction is because of a hill . Now that is on the road I haven’t tried to see how far out I’m reaching going through the woods. My guess on that is I would reach out further because I could get on hill tops etc. on the road I can’t do that. Also I didn’t mention the distance I was getting with the U25 amp was also during the summer with all the foliage on the trees. I’m assuming that if I upgraded my antenna & power converter and switched to a 50watt radio I most likely would easily reach out 10 mile radius around my base radio . That’s talking the roads around my house. That said through the woods and staying on the ridge tops I could go further. Maybe that bit of information will help you guys have a better idea of what I’m dealing with. I have also went to a bigger coax . It’s not LMR-400 It’s Brownings equivalent there version of LMR-400. Eventually I will , after I get a better power converter,50watt radio and the proper antenna for my area’s conditions I’m sure in certain conditions I might be able to 2-3 miles to what I’m getting now. Still I would like to here from you guys. Sent from my iPhone using Tapatalk
