New antenna technologies are being developed that allow an antenna to rapidly change its pattern in response to changes in direction of arrival of the received signal. The following answers are from Reginald (Reggie) Driscoll WA6ZAP: For a start, read National Electrical Code Article 250 - Grounding, re: Earth Electrodes and the requirements. The thing that's preventing me from going forward with the job is that I'm not sure how to then bond the antenna grounding rod to my home electric ground. SWR alone doesn't dictate much about performance, or even the necessity to ground the station. Comparing the efficiency of a small vertical with a small loop antenna one trades ground. The rods should be mounted parallel to the each edge and extend approximately 15 inches beyond the edge of the aluminum square. Don’t create any splices or connections in the ground wire between the mast and the ground rod. That surface, whatever it is, forms the actual ground plane, albeit rather lossy. A totally different approach to low frequency antennas is shown in fig. There is much confusion about grounding antennas. 25 short (6-12") ground rods spaced approximately 4' apart and interconnected in series by a 100' length of heavy braided wire or wide copper strapping. That's what I use for one gutter antenna that is fed up on the roof, coax shield just not connected up there. However when it is not possible to ground mount an antenna because of ground conditions or it is necessary to elevate the antenna, another solution is to use a ground plane. 8 out of 5 by 76. Most radio antennas require a ground plane. A ground rod and its associated radial system are necessary to protect your equipment from nearby lightning strikes, static discharges, and to provide the "missing half" of your vertical antenna system. Complete with ground rod, ground wire and coaxial ground block. Do I have to install a grounding rod every 20' and connect those rods to my service ground?. Special clamps that provide a solid connection between the ground wire and ground rod should be used. It is an excellent all-around 40 meter antenna for those who don’t have room for (or can’t afford) a yagi, but want more than an inverted V. The antenna has a low SWR (less than 1. This system is very efficient. This method is the simplest of the. It is proofed for long times that it is useless to add too many radials at ground level to increase the efficiency of an antenna, because there is a much better solution : raising the antenna above ground to benefit of better performances ! Second part. K40 CB Antennas quality, time tested CB and 10 Meter radio antennas that are durable and rugged and carry up to a 5 year guarantee and a money back warranty. now that that is over with, If I had your situation I would run an aluminum solid wire I bought at Home Depot that they sell for antenna grounding from the base of the dish mount that is bolted to the wall by the shortest distance over the porch roof and straight down the wall to an 8 foot ground rod driven into the ground next to the. The station ground and "electrical mass" of the tower and amateur antennas look like a much better ground than a typical small ground rod at the service entrance.
