Here is a website where you can enter two points to see the path between them. It also allows you to make adjustments for elevation of the antenna.

In my experience, the RF path for GMRS isn't purely line of sight. I have generally been able to get over or around small hills successfully, but not bigger hills.

Your success in reaching the other side of town will largely depend upon how big the "dip" is on the other side of the high spot. If it dips down to 350 feet, you'll probably be fine, but if it dips back to 130 feet as it does on your side, probably not.

Ya it dips back down to 130/150 feet.

GMRS operates on a line-of-sight basis. If your transmitter antenna can't "see" the receiver's antenna i a straight line, then they will not communicate. There are websites that will provide you with a path outline base on the gps location and elevation of both antennas showing any obstructions such as hills.

Anyway you can send me a link to them sites?

Hi everyone. I’m pretty sure I’m answering my own question but just looking for confirmation.  My base is 130 feet above sea level. I’m trying to reach the other side of my town and the elevation between me and what I’m trying to reach is 380 feet than it dips back down.  Would my antenna need to be 250 feet in the air to do what I want to do?

I assume you already have a ground plane UHF antenna on your truck? Do you have any kind of home antenna deployed? Before you buy a repeater or any more radios. work with what you have first. a simple SMA to BNC adapter will allow you to use external antennas, You could have a Home ridge line antenna install and easily connect to it when you get home. That Tera radio is a nice set up. get some feedline and a yagi antenna for your home base, maybe a rotor if you have local friends or family you wish to communicate with. Consider learning to build your own base antenna. there are a lot of options if you are hesitant to spend a lot of money,. check your metal piles, I keep lot's of stuff that could be used to build antennas.

 

I do have a UHF for my truck and no I have nothing for my home.  so I should mess around with an antenna before anything else? only issue with an outdoor antenna is I live in a condo... would an attic antenna be worth it?

Hi everyone, before I go on I have spend hours on this forums and a few others trying to answer my questions. But I'm try to figure out how to get the most out of my handheld radios. I live in southern NH and from what I can gather a repeater doesn't exist around me. I bought external antennas from powerwerx and I can get about a mile out of them. Im looking to get 5 miles if I can get more than that's great! I have been looking at the midland mxt400 and setting it up in my truck as a repeater. is this a possible route for me or am I missing something? I don't have the programming cable for these radios yet. looking to get some feed back before I start ordering things. 

 thanks for your time!!!
