PMR446 range

I keep hearing people say it's all about the power of the radio,i say no it's not,antenna and the height of the antenna is 100% what pmr446 is about,you could have 100 watts running into a huge beam or collinear but if that antenna is not above everything like roof tops then it just won't work,never forget uhf is line of sight so the antenna needs to be up as high as you can get it.

What is the best PMR 446 antenna ?

The best PMR 446 antenna is a collinear,because of the gain,no other antenna apart from a beam comes close,so i hope this helps everyone who keeps asking me this,oh and another thing when i say pmr 446 collinear i mean for pmr 446 not one of them dual band collinear for ham radio use,they won't work well at 446 because most are 2 meter collinears that only work on the third harmonic on 70cm's which lands on 432mhz,as you can see 432mhz is no where near 446mhz.
