OK what frequency should I get?

Hi everyone. I'm looking for a fpv system to start with and I'm not sure which frequency I should use. I have to consider obstacle penetration because one of the areas I want to fly in sits a low bowl surrounded by 4000 foot mountains. It is heavily forested. I think there's some significant radio activity, family radios and stuff around. What frequency should I consider? I'd like to be able to fly a few miles. Would the UHF be best or would the number of channels be limited? I'm getting a ham license. Thanks

For penetration I would get something like a 1.2ghz FPV system with a high gain antenna such as a helical or a patch. For the UHF I would either get Dragon Link or EzUHF.

Start with what is your flight rc frequency? If 2.4, you are kinda stuck with your choices without some filters and additional setup.

If you are using DSM2/2.4 don't use 1.2ghz. If your planning to get UHF you can.

I'm using 2.4g with 1.2g Video with SAW filters in the Vrx and have no problems.

What would be the most effective flight frequency for a forested area with lots of mountains around it. I've heard great things about the ezuhf system and the dragon link. Would a UHF flight system and a 5.8ghz video work well?

If you dont mind some programming with usb tools get the Open LRS system. Its what I am going to try. Purely for budget reasons and a few guys are having a good run with them.

How does this sound for a beginner. Stick with the Spektrum 2.4ghz system for the flight controls and use a 5.8ghz for the video. Would I be able to get a healthy mile or two with high gain antennas? Then as my skills improve move up to UHF? I'm very familiar with the area I'm in. I've flown over it many times in full size aircraft so finding my way around wouldn't be too hard I don't think.

A lot of guys do start out with 5.8ghz. It is a pretty good freq, get a nice blue beam for the Vtx and a helical/crosshair for your goggles. Or even a set of bluebeams, cloverleaf and skewplannerwheel. Yes you may be able to squeeze a mile or so from the video, but not sure about your radio.

Don't make the mistake of jumping in and going for distance. Get to know your set up and you have to trust it. Fly LOS with a friend on the goggles at first, to make sure all is ok, then still fly LOS for awhile with a spotter, after you get comfortable with your surroundings, trust me is easy to watch videos all day long and think, hmm year that cool, looks easy...its a differant when you doing it...
With time you'll get out to some distance, distance is boring anyways and a longer walk..Proximity is where its at... lol

Have a watch. Might be a good idea to watch the entire series. He goes over a ton of info.
