Hi guys, I think this is getting off track mostly becouse of many peoples missconception about RF Power. Seems that if you have 50 watts, and can talk 50 miles, then 200w would there for talk 200 miles right? Wrong! 200w over 50 watt is only 6db so if in tern you had a 1/4 wave on your car and can talk 50 miles with your 50 watt radio, would you then expect to talk about 200 miles if you changed it to a 5/8 antenna? Of cours not right? (Most 5/8 are typicaly 4 to 5db, so you kinda ket the idea right)?

The antenna doesn't know if it's receiving or transmitting - so the antenna has absolutely nothing to do with transmit or receive balance - which is now the subject. Kevin Custer
