There is also a HUGE difference in 8' antenna's. You know the saying 'you get what you pay for?' Well you do. Get the higher db gain antenna, its worth it. Also like stated, mount it as high as possible, for the best range. I can talk to the Thames River from Schmid marina to a friend of mine who has the same antenna, like he is right next to me. I have a hand held also, works good on the dinghy when toolin' around.
