150 mhz = 6.913 db improvement
450 mhz = 7.756 db improvement Antenna tip 15 feet higher Now here's my question - will I notice the improvement enough? I've had several OM's tell me that on SSB, CW or HF I would but not on 2m/440 simplex and repeaters. Ken KG0WX Well, Ken maybe your "OM's" didn't eat their Wheaties. A 6dB improvement means you have quadrupled your ERP over your existing system. You have also increased the distance to your radio horizon with the increse in antenna height. Why they would say you won't notice an improvement is beyond me. In plane language here are a few things just a 6dB improvement mean. You can reduce your radios Tx power by a factor of 4 and have the equivalent ERP, 6dB doubles your range Tx and Rx (within the limits of your stations LOS - line of sight). Stations that were noisy will now be full quieting, be it simplex or repeaters you work. In even simpler terms, "night and day". What are you waiting for?
