I use either Baofeng UV9R Plus or UV5R radios.
When we are away at events we have the frequency 458.825 allocated but we had really bad comms last weekend I am wondering if there would be better radio’s or even just changing the antenna’s would improve our reception?
Our location varies from flat urban land to Hills and valleys, we only need about 5K max distance the issue is the undulation and if the standard baofeng antenna’s are the right thing to use.
If it helps the only GSM signal we get on site is EE I was thinking about buying radios with sims to use apps like Zello but not sure what to go with.
Any help is appreciated thanks.
