Grounding Transceiver Second Floor

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.

Grounding transceiver second floor.

You have to deal with both situations. Stations on the second story or higher have a unique grounding problem. The author s shack is in the second floor and uses the same grounding system which has been in use since 1989 with no rfi in the shack even when the 1 kw linear amplifier is in use. If one has an artificial ground box and the wire to ground is 1 4wl neutralizing the reactance will not help as the rf resistance is sky high.

Lead lengths to the grounding system are much too long to provide a low impedance rf ground. That s a lot of noise. Be sure to read the rfi grounding page. The best place for the rig is the basement followed by the 1st floor.

Rf in the ham shack. Second floor grounding home up house ground layouts. This could be a major problem if your shack is on the second floor or higher. There is also a belief that a good equipment rf ground improves our transmitting signal strength and the.

It was 18 db above my antenna s noise floor and 26 db above the receiver s noise floor. Safety grounding of your transceiver. If you wind up on the second floor like me then be sure to get. This sort of disagreement about ground potential is characteristic of electrically noisy environments.

It is commonly assumed rf in the shack interference to consumer devices like telephones or stereos or even rf feedback or rf burns result from poor operating position equipment grounding. If a ground wire is run from the second story to earth ground it needs to be a multiple of 1 2wl but like the 1 4wl counterpoise it will radiate just like an antenna element. Last night this measured about s5 5 which is about 93 dbm preamp off 6khz bandwidth. Although proper power grounding is fairly straightforward for ac and dc power grounding for the radio signals in a ham station is a different problem altogether.

The common problem with the rf ground from the second floor appears to be resonance which would mean giving up certain bands i believe. 3 points 1 year ago. We used a 01 μf 1kv capacitor for c1. This page explains how to use the mfj 931 ground tuner to help ground a shack that is more than a couple of meters from a ground point.

I had a second floor shack in the 70 s my station ground was made of 8 stranded insulated copper wire that ran 10 ft over to the wall and about 10 ft down the outside wall to a single ground rod i never ran more than 300 watts my antennas were a couple monoband beams on a tv tower about 60 ft away and an inverted vee about 20 ft from the outside of the building i never had any.
