Hey guys just installed my first beam antenna this weekend that was purchased from copper along with rotor and bearing,,Always ran Maco ground planes and never tried a beam.Was wondering do beams take time to break in?. First night I talked on it I noticed increased static only on ch40,Then the next night static on 41..(27.415),Curious if anyone has had this issue Antenna is vertical bout 32 feet in the air swr's are 1.4 cross the band any info would be great thanks... |

Antennas do not have to "break in". However, sometimes, aluminum antennas take time to wear in from wind when the aluminum tubing wasn't first cleaned during assembly. The aluminum tubing joints almost always need to be cleaned prior to assembly.

I use steel wool to clean my joints when I put a antenna together no matter if it is new or old. makes a better connection. |

I didn't know that LED TV's caused noise. I did know that the Plasma sets did. Thanks for the info.

The LED backlit TV's don't seem to make much RF noise (except for switching power supply noise typical of all new style TVs), but the new generation of LED TV's that use millions of micro-size multi-color LED's to create the image really do.
Most of the time, the noise is created by power supplies or processors. If it's power supply, it's possible to suppress some of the noise. If it's processor, you have to do internal surgery to suppress any of that.
