The yagi plays the role of a ground plane, while the tower plays the double role of ...Your power supply should have a 3 pin plug on it for connection to the building AC; one of these pins (usually the round one) should be the "safety" ground running back to the distribution panel and its earth ground. You should have no trouble here unless you mount your radio to the power supply (keep them isolated from each other). The general idea is that for maximum effect you will need multiple ground rods spaced 8-10 feet apart and all connected by a large diameter wire (#6 or larger). Do not use stranded wire or braid if possible due to the fact that at RF the wires work individually instead as a single conductor and they can also be broken easier. So I have all of my antennas mounted up in my attic(1 vhf/uhf vertical, 1 2M Loop, 1 6M Ham stick, and 1 HF Dipole). There is not really any concern for lightning, but I have heard that grounding your antennas will cut down RF interference. I designed a plan to ground my antennas but I have second thoughts about how or if it will really work.Route coax under the truck for a couple of feet attaching to existing lines/brackets. Pull the driver's rear rocker panel. pop one of the small gromets. Feed coax up and through the gromet. USE WATERPROOF TAPE or something similar to seal the opening. Route coax through rocker panel to its final destination.The easiest is to ground your antennas and tower so that a lightning strike will go into the ground and away from your house. Antennas should be ground bonded to the tower and the tower bonded to an eight foot ground rod buried at the base of the tower. 10 gauge solid electrical wire is heavy enough for most antenna systems.HAM RADIO VHF/UHF MOBILE INSTALLATION by Mike Baker, W8CM . Three categories: 1. DC power ... REQUIRE A 'GROUND PLANE' FOR PROPER PERFORMANCE This affects the mounting location, and ... a good ground connection for the antenna and coax cable . Insert the coax from the topFor a final step to make sure there's no electrical and/or grounding problems, you'll want to do a system wide continuity check.

A minimum of 3 ground rods in a triangle are required -one will ...Run a ground wire from it common ground rod where the electricity enters your house. Note that you do not have to run the ground wire from the antenna, you can ground the boom to the coax using a grounding block, and at the other end run a ground block and grounding wire to the main ground. This works electrically, it may not be legal in the US.A single four-foot ground rod, driven into the ground no more than 12 inches from the base B. A ferrite-core RF choke connected between the tower and ground C. A connection between the tower base and a cold water pipe D. Separate eight-foot ground rods for each tower leg, bonded to the tower and each otherChange the location of the bonding wire, or coil up an excessively long cable. Add ferrite RF suppression cores to the cables. On the higher HF bands (particularly 21, 24, and 28 MHz), cables and wires begin to look like antennas as their lengths exceed ⅛ wavelength. A 6-foot data cable, for example, is about 3/16 wavelength long on 28 MHz ...One of the easiest solution is to paint your fiberglass antenna. The first thing you'll want to do is drop your antenna down, either on the ground or on some sawhorses for painting (it wouldn't make much sense to go up and down a ladder to try and paint it while it's mounted). You may opt to tape up certain areas of the antenna prior to ...Safety in mounting mobile antennas and anything else on the exterior of you vehicle is a primary concern. This was discussed in some detail during the presentation. The best source to understand safety considerations and proper installation and mounting of Mobile HF antennas is Alan Applegate's excellent website, K0BG.com. The most important part of any Amateur Radio Station is the antenna ...The height of your Antenna is important for ham radio contact, so if your ham radio antenna is low to the ground then it will have less ham radio signal. The best height for a ham radio antenna is between 10ft – 15ft off the ground. The ham radio antenna should be higher the further away you are because ham radio signals follow a straight line. Your ground wire is 30 feet long (9.1 meters); this length is very close to a quarter wavelength at 7 MHz. When you start transmitting at this frequency, your transmitter setup and antenna system will create an image of standing wave throughout the length of this wire. This is by virtue of the RF voltage induced due to resonance.This article will cover the second phase of our Mobile HF project - bonding and grounding.The following is a summary of the phases of the project: Phase 1 - Install the Icom IC-7000 running barefoot with a simple MFJ HAMStick Antenna (to be replaced with the Scorpion Screwdriver Antenna in Phase 3) Phase 2 - Properly bond all…Position a non-inductive resistor across a non-conductive portion of the mast if your concern is bleeding static charge from the antenna.

The Test Our 40-foot sailboat was professionally outfitted with an ICOM marine SSB/ham transceiver .The automatic antenna tuner was an ICOM AT 130, and the ground system was a professionallyGround plane availability is another critical factor in mobile antenna performance, and must be considered when determining the location and type of the antenna. Ground plane requirements vary given the type of mobile antenna and the frequency of operation. A typical 5/8 wave antenna at 150 MHz requires a ground plane of at least 42" in diameter.The receive signals were very much better when I grounded the radio to an outside ground rod. I was using a dipole antenna at the time. Later, I was operating an IC-706MKII. I had an S-7 noise level and lots of noise from my computer and other things in the house. I had a ground rod outside my window so I decided to use it to ground the radio.The radio relay has a wind and dustproof casing; the antenna is protected by fiberglass pipe; and the radio relay kit is durable and can be used in a variety of environments; easy maintenance. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon.For a final step to make sure there's no electrical and/or grounding problems, you'll want to do a system wide continuity check. This will help you spot any potential chassis grounding issues, or other unexpected points where the antenna is failing to ground properly. To do so, follow this guide to performing a system wide CB continuity check.If the ground plane's four radials are parallel to the ground below, the antenna's impedance (atop a tower) will be around 22 ohms. You can raise the impedance to better match a 50 ohm coax transmission cable by sloping the radials downward away from the vertical element. A 45-degree angle usually works well to that end.Ham Radio Deluxe is the World's Most Popular Ham Radio Software.

I designed a plan to ground my antennas but I have second thoughts about how or if it will really work.It also prevents a minor ground loop between the leads. It should be noted, that in some cases, the battery's chassis grounding point is inaccessible. If this is the case, attach the transceiver's ground connection as close to the battery's grounding point as possible. There are a few other related issues to be discussed.The DXZone merges amateur radio and Internet, since early internet days. Established in 1996 as a radio-related-mailinglist, has registered its domain name in 1998. Main goal is to review and promote ham-radio web sites, classifying them in categories. The DXZone is managed by ham radio operators with ham radio operators in mind.If the ground plane's four radials are parallel to the ground below, the antenna's impedance (atop a tower) will be around 22 ohms. You can raise the impedance to better match a 50 ohm coax transmission cable by sloping the radials downward away from the vertical element. A 45-degree angle usually works well to that end.The ground for the mast should be as direct and short as possible, with minimal bends, using a minimum of 10 AWG copper wire (or 17 AWG copper-clad steel or bronze wire). It can be connected to the GES using a split bolt connector available at most hardware and home centers. The coaxial cable that comes from the antenna also needs to be bonded ...level 1. · 1 yr. ago. Essentially what you want to do is run a ground wire (bare or sheathed, it doesn't really matter tbh) from a connection point on your antenna, to a ground rod that is driven about a few feet into the ground. An electrician probably wouldn't charge you too much for this, and you can rest easy because it'd be done right.Carefully cut the existing wires close to the base of the antenna leaving about 2 inches. Attach a male Molex connector (2 or 4 pin as required), or use Anderson Power Pole connectors. When you wind your choke (s), use mating connectors to extend the leads. This makes antenna removal easier too.How the radio frequency spectrum is used. The radio frequency spectrum includes the set of frequencies of the electromagnetic framework ranging from 30 Hz to 300 GHz.
