Ham Radio Sheet Metal Ground

And you are actually ready for the future or for antennas not utilized with boosters too.

Ham radio sheet metal ground.

Zip wire primary wire. A very large pizza sheet might be around a meter in diameter or iow 50cm in radius. Anything shorter than a 1 4 wave can still work but it will change the tuning eg the feedpoint will no longer be resistive. Ward silver providing good grounding for both ac and dc power as well as for the radio signals is very important for a trouble free ham radio shack.

Safety stand tower platform. Since you really only need four radials and not a continuous sheet of metal the distance to the four corners from the center of an 8 x 8 metal sheet is 5 7 meaning that you have plenty of ground plane for the job. That s only 05 wavelengths at 30 mhz which is a tiny ground plane. Unless the radius of the ground plane is a 1 4 wave it s not operating as a true ground plane.

Antenna wire build your own antenna components. Exothermic ground rod welding materials. It also depends on whether a ham is trying to hit the local 2m repeater one mile away or bust a dx pileup on 20m. Bonded to house ground if distant from house it should not be bonded to house ground coax shield will provide inductive connection so most lightning current will go to tower grounds distant 200 ft cable run from base to house.

Tower and antenna books. How to ground power and radio wave frequency in your ham radio shack by h. Ideally that ground should be at the connector entrance but often it is located up on some board near an audio preamplifier. If an external device is connected to the mic jack and that external device grounds the mic shield back to the station ground or power mains safety ground it will introduce hum into the audio.

A metal pan that is 38 inches in diameter would work well for a 2m ground plane but i have had trouble finding a 66 foot diameter metal pan for a 40m vertical. A cookie or pizza sheet works fine as a ground plane for a 70cm or even 2m vertical but it s a very small ground plane on 10m or lower bands.
