org The … K6MYC on Antenna Testing. antenna in free space is broadside to the antenna. Being a half-wavelength on that band, the antenna pro-vides an efficient low-angle radiation pattern, with roughly a dB of gain over the shorter standard quarter-wave vertical. 06 feet. Length of vertical in feet = (for half-wave dipole) _____ 468 f (MHz) Feet = 468/50 = 9. The 6 meter Moxon is built from 5/ 8 inch OD and 1/ 2 inch OD aluminum tubing with 3/ 8 inch OD solid aluminum for the corners. John Portune, W6NBC My last vertical antenna experience relevant to the Hex Array came from the MFJ-1792 antenna. Next step for me is a 10 meter antenna - I haven't decided what to build yet. 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. Although this design has been around for a long time, it is only gaining popularity now due to the recent improvement in high power antenna tuners. The formula for the elements is ((460/f) / 2) where f is the frequency.
This vertical antenna may also be tuned to provide outstanding reception in the SWL 11, 13, 16, 19, 22, 25, 31, 41, 49, 74, and 90 meter bands # Also fabricating parts for a 6 meter Moxon antenna. No endorsement may be inferred from the mere listing of a URL or link. Â I have not done this. 2006) might do the job. The RF power wave reshaping help taking some of the RF power emitting vertically to the horizontal radiation. The antenna displays a low feed impedance, which allow you to feed it directly with 50-ohm coax cable. ). 1KW max power No ground radials needed. Model of the antenna was simulated by RW4HFN. Reviewed by Bob Allison, WB1GCMAssistant Laboratory Managerwb1gcm@arrl. Some local interest in 6 meters started up when the emergency group was looking for a frequency to connect 2 sites that are just out of VHF range and did not have equipment or space for HF antennas.
MFJ-2990 . A very compact antenna for the 4 and 6m band. The Horizontal Loop, also known as the Loop Skywire Antenna, is an old but very effective design. What’s more, with proper matching, it also performs very well on the 20 meter band. However, for local communications out to 50 miles or so using omni-directional antennas vertical polarization is better than horizontal. So in this case, we want to build an antenna for 6 meters, 50. Here is a Tri-Band 6/2/440 Collinear antenna that if built properly, using the materials suggested by the author, should give you years of service. E. 6 Meter 5/8 Wave Vertical Antenna By Mike, G3JVL. What makes a antenna better? The Slim Jim Antenna is an end-fed folded dipole antenna that has a gain of 6 dbi and a nice low RF take off angle. Having purchased an all-mode, all-band (160m - 70cm) transceiver, I became curious about what 2-meter weak signal operations have to offer.
85 $ 481. Antenna does not require any tuning elements. By: W8CWE. A quater wave antenna's radiation pattern like a dome. If you use 50-ohm coaxial cable as your feed line, you'll need a matching device at the base of the antenna to make the antenna work correctly. Part of the issue is the requisite inductance of the coil. But I'm getting ready (saving up) to get a 10 meter ham radio and will be needing a base antenna for it. This antenna is an excellent performer, and ruggedly built. Page 121 of MFJ new 2013 ham catalog Hy-Gain’s PATRIOT HF vertical antennas are the best built, best performing and best priced multiband verticals on the market today. The line should run horizontal for 40 feet or more. Antenna is outperforming any 6 meter vertical, I believe, on the market.
82 feet 6. There have been questions on one of our local repeaters about operating on 2 meters while living in an apartment. Here's a 6 meter (metre for my European friends :-) lightweight Moxon antenna I built. 3 metres long which is an ideal size for hand-baggage on aircraft. 86 Mhz 3rd Harmonic Halfwave in space is: 9. Â No change to the gamma arm will be required if this antenna is altered for 6-meter FM. Eventually I'll cough up the $$ for a good HF rig. The 6 m vertical did show a small-but-noticeable advantage. 6" 10' 7. Antenna gain is measured in either dBi or dBd. Base antenna systems for amateur ham radio HF VHF UHF - Performance, Quality, Service I needed to replace my old 2 Meter 1/4 wave vertical antenna for the 146 mHz.
