  • Just wanted to let you guys know that the matching coil DXE-VMN-1 worked quite well with my 1/4 wave vertical wire antenna for 80 meters. I had some matching problems using toroid transformers (un-un) to match the 20 ohm feed impedance and once I set up the DXE-VMN-1 with my antenna analyzer, the antenna matched at 1:1 SWR across a 150 Khz 2:1 ...

  • Finally, a mast mount version of the 11 meter "collinear" CB antenna is available. No other omni directional CB antenna can come close to the gain of this antenna. Typically has 6 db (approx), over any other 5/8 wave antenna. It is designed to have extra long range communications, due to its very low angle of radiation.

  • Sep 24, 2018 · The J-Pole antenna, more properly known as the J antenna [6], is one of the most popular antennas for 2m vertical use in the amateur radio ranks. It has been around for many decades [1]. I have covered J-Poles quite a bit on this site [2]. My favorite feature is the versatile feed adjustment provided by the J part of the antenna.

There are two kinds of antenna length. (1) the antenna’s physical length and (2) the antenna’s electrical length. Physical length refers to the length of the “non-conducting” whip while the electrical length is the “operating” length of the antenna based on its electrical structure. You need to determine how much range you’ll need.

Most designed discone antennas are broadband-type antennas and generally have unity gain. Since 6 meters, under typical conditions, depends largely on ground wave propagation, getting a unity gain antenna up as high as possible to extend the over-the horizon propagation, is always a good idea.
6 Meter Beam Antenna. 1.5 KW Power Handling Capacity. Transmits and receives in an uni-directional (one direction) pattern. The Gizmotchy® 6 Meter Power Booster consists of another set of director elements identical to those on the antenna plus an extension boom.

For instance, if a radio wave passing a given location has a flux of 1 pW / m 2 (10 −12 Watts per square meter) and an antenna has an effective area of 12 m 2, then the antenna would deliver 12 pW of RF power to the receiver (30 microvolts RMS at 75 Ohms). Since the receiving antenna is not equally sensitive to signals received from all ...
