The Wave Missle HF Antenna Project by VE1COR AND KB1RSE
13/09/2018 · In this Article: Using a Coaxial Cable Using Speaker Wire Community Q&A References This wikiHow teaches you how to create your own FM antenna in order to increase your FM receiver's range. Depending on your preferred range, you can do this by using either coaxial cable or speaker wire.... Enter the shorted 1/4 wave stub! The drawback to this type of match is the fact is it monoband in nature. While you can cascade (parallel) stubs in some cases, the mechanical considerations become a headache. If nothing else, it is a lot less complicated than using an internal or external auto-coupler with about the same results.
2M Slim Jim antenna using Aluminum Tubing HAM RADIO
The feedpoint impedance of a full-wave loop in free space is aproximately 100-120 Ω with a gain over a dipole of 1.35 dB. In the real world, installed at practical amateur heights (physically close to ground), the range of feedpoint impedance can be from 50-240 Ω depending on configuration, orientation, and choice of …... The MFJ-259B Antenna Analyzer is an ideal piece of equipment for tuning a Hustler® BTV antenna. Measurements should be made at the antenna using a short (5 or 6 ft) piece of 50 Ω coax between

1-1/4, etc.) and short circuited for all half-wave stub multiples (like 1/2, 1, 1-1/2, etc.).: If a balanced line is used, operate the MFJ-259B only from internal batteries. Keep the MFJ-259B a few feet how to change floor type in rimworld 31/10/2003 · Cut the leads as short as possible but adequate for insertion and soldering into the SO 239 coaxial socket.

The use of an antenna analyzer such as the MFJ-259B will facilitate the fine tuning of the vertical. Ground conductivity as well as the number of radials and their length can affect tuning parameters.
- Anyone have experience using an MFJ 259B analyzer to determine the resonant frequency of a coaxial trap? Specifically, I'm looking for guidance on the
- Using the example above, you need a 14.219 foot jumper from the radio to the SWR meter, and a 1/2-wave multiple length from the SWR meter to the antenna. If my antenna is 65 feet away from my radio, I need a 14.219 foot jumper from the radio to the SWR meter, and a 71.095 foot length between the SWR meter and the antenna.
