I'm building a bumper mounted antenna tower, EMT with some square tube. Earlier today I stumbled across an article on 2 meter slot antennas cut in to satellite dishes. Literature is repetitive either directed towards that subject or TV and UHF broadcasting. I like the idea of a Dipole analogue that doesn't look like an antenna... The phasing harness allows 2 or more yagis (beam antennia) to be co-phased or bound together as if they were one single much larger antennia. By phasing 2 yagis together you can increase your forward gain by at least 3dB, increase your front-to-back ratio and decrease your pattern width (narrow your beam). THE HALF WAVE VERTICAL. Probably the best know antenna on our 11 meter band ! Everyone has used this type in the past or will use it somewhere! Although the half wave vertical comes along with various names the PRINCIPLE is all the same. (1) antenna mount with internal threads to accept 3/8″-24 antenna element. I used a Radio Shack CB antenna mirror/luggage rack mount because it was the only antenna mount available locally. Here you see the actual antenna mount disassembled and removed from the mirror/luggage rack bracket.

This calculator will help you to calculate the different wavelength of antennas based on the frequency. Nov 17, 2008 · I use a CB SWR meter to check 2M antennas all the time. There is a trick to it however. If all you want to to is check SWR on your 2M antenna, you don’t necessarily have to buy a dedicated VHF/UHF SWR meter. What I keep in my toolbag for that is a cheapie $5 hamfest special CB SWR meter. I had a dipole up for 4m previously (see here), which worked fine, but was quite ugly on a 1 metre boom arm. I wanted to make something simple that would be reliable and not require a balun or any impedance transforming, so I decided to build a quarter wave ground plane antenna for home. building one of the antennas, you can get one ready to install.l The System Fig 1 shows a schematic of a glass- mounted antenna system. At A is the elec- trical equivalent of a 1/4-X antenna. Why the need for L and C, and how does the signal get from the coax to the antenna without a connecting wire? The reason— and the way—is capacitance. Follow this guide to test your CB coax for problems. #9 - Test Your Antenna for Defects / Opens.

Amateur Radio operators have distinguished themselves by their ability to build equipment from junk and bits and pieces found around the house. Station Master Antenna Notes, by Karl Shoemaker, AK2O . Introduction. Antennas are an extremely important part of a radio station. They provide performance to radiate R.F. out to distance receiving stations. I am Jeffrey Cavender and I founded Breedlove Mounts. I make and sell a wide range of brackets and antenna mounts for your mobile ham radio operators. We have been providing variable and straightforward mount devices since 2002. Your first antenna – the half-wave dipole. Many hams’ first choice of antenna is a half-wave dipole. But don’t be misled – just because they are easy to make doesn’t mean they don’t work well. In fact, a half-wave dipole will often outperform many compromise commercial multiband antennas. 2 Meter Antennas at CB World 2 Meter Antennas: Stretching from 144MHZ to 148 MHz, the 2 meter amateur radio band is a portion of the VHF radio spectrum. Here are some 2 meter antenna options for you! Recycling TV Antennas for 2-Meter Use “Green” that aluminum into something useful right in your own backyard! By Ronald Lumachi, WB2CQM Just as quickly as cable TV companies wire up neighborhoods for CATV service, home owners remove TV antennas, masts i home-brewed a GP using a maco type tuning ring . it was a very effective antenna . my vertical was taller though . i tried 22 1/2 ft and 23 ft but i didn't see any difference between 5/8 and .64 wave lengths . i had 108 inch sloped ground elements on it . i also used a one piece tuning ring . i made mine out of 1 inch x 1/8 inch thick aluminum strip from lowes . Example: if you have an antenna with a 7 db gain, coax with calculated loss (based on type, length, and operating frequency) of 2 db, and total connector losses of 1 db, you have 7-2-1 = 4 db of gain. Thus, if your rig is transmitting 100 Watts peak, you will have a peak ERP of 100 x 2.5 (multiplier) = 250 Watts. The antenna (not radio!) is primarily what determines how far your CB can send/receive - so invest wisely Longer antennas - and those mounted higher up - perform best To learn more, see our comprehensive guide on picking the right CB antenna 0x801901f4 bitsARRL Product Review of the M2 6-Meter HO Loop Antennas.
