Post help..tuning a comet antenna Reply with quote
ok i recently got a 30 watt amp for my max pro! , i have a comet antenna,
and its all setup, my signal comes in clear for mabe 1 mile or less! , i dont know whats up with it, is this because i never tuned my comet antenna? and if so how do i tune it? , my antenna is on my two story house on the roof and its weird that i only get 1 mile! can someone help me , how can i improve that , and how do i tune my comet antenna, this 30 watts is seeming no better than my 5 watt transmitter , but im thinking its just the antenna is not tuned correctly, please help,

Sounds like you may be getting exceptionally high SWR (due to antenna problems more than likely). To tune the comet antenna you adjust the height of the upper element according to the frequency you are operating on (i'm not sure of the measurements offhand, someone please post them here). Hmm, you should have received a small paper with tuning instructions on it. Pretty simple stuff. For fine tuning and optimal performance you should probably get an SWR meter and measure everything out, though it's not absolutely necessary. Hope this helps!

ok so say i put the height of the upper element as high as it goes, would that make it 108MHZ and say i dropped the upper element as low as it goes , would that be in the 88MHZ range.. please help me i would like a idea of how it works , thank you

I'll do some research on the net for you, and post my results on here. I can't remember the exact measurements.
