PMR446 any good ?

Heres my answser,it depends on where you live and what setup you have,if you want to hear and talk for miles around you then you need a out door antenna such as this,once you have a antenna you need to put it above your roof for it to work any good,having it in your bedroom just isn't going to work well,so to clarify your base station antenna needs to be above your roof,if you do it right and have some nice low loss 50 ohm thick coax (check this blog for the best coax) then you can expect a good signal for miles around you,don't forget it depends on output power of the radio or handheld you are using,for 1/2 watt you can expect around 10 miles maybe more depending on your location,if you are looking down on a city then you can expect to work most of it,pmr446 is all about line of sight,so what ever the antenna can see it should work and now you know why you can't talk for miles on a little handheld in your bedroom,i've heard people say that they can talk everywhere on their mobile phone,yes but did you know your mobile phone goes through a very local repeater ?
