Antena gp 2m 70cm j-pole


Awesome guide! Will recommend to friends. Thanks again! The collinear J antenna improves the Super-J by separating the two radiating half-wave sections to optimize gain using a phasing coil. Instead, buy the best antenna system feed line, tower or mast, ground system, antenna itself you can afford. Today I watched your post on the tribander hand held radio. Just use the formula divided by frequency for the length of your elements. I always planned on using a mag mount antenna on a cookie sheet if I ever had to down-size to an apartment. Some repeaters I thought were not active on my handheld I have found active now!

    About SWR. My OSJ / J-Pole went through 3 hurricanes in 6 weeks, with gusts speeds, on occasion, as high as MPH. No damage at all, and it kept.

    Like all antennas, the J-pole is sensitive to electrically conductive objects in its induction fields [8] aka reactive near-field region [9] and should maintain sufficient separation to minimize these near field interactions as part of typical system installation considerations.

    The J-pole antenna is an end-fed omnidirectional half-wave antenna that is matched to the feedline by a quarter wave parallel transmission line stub [1] of Lecher system form.

    The top one is a strong copper brass wire of 5 to 7 mm diameter soldered directly to the coil and mounted to the PVC isolator to give a strong construction. The collinear J antenna improves the Super-J by separating the two radiating half-wave sections to optimize gain using a phasing coil.

    But how well do these perform? Thanks for the info.

    Michael D Mayne verified owner — August 13, The Super-J reveals the benefit of properly phasing and orienting a second radiator above the first. J-poles don't, no matter who made them. Bill S.

    This is also a nice ham project, een small antenna for 2m and 70cm, after using it This easy to build dual band VHF/UHF antenna makes a great antenna for newcomers because it has better performance than a GP and is.

    Real measurements of a Slim Jim antenna and traditional j-pole antenna his 2BCX Slim Jim with a 5/8 wave GP, while perfectly reasonable and Also, does the comparison change for 2m or 70cm as all the data was.

    It performs almost as well as my old Diamond X did before I sold it. Will recommend to friends. Steve Simpkin — July 19, Love the antenna, made getting on easy.

    If you enjoyed this article, why not subscribe to our newsletter. To build this antenna, we first need to make a couple calculations for the length of our radiator and radials.

    Ken K. Is one better than the other in certain circumstances? VHF Airband. Great antenna.

    Slim Jim vs. Traditional Jpole Antenna

    Pin It on Pinterest. I received my J-Pole today and installed it, and immediately started contacting people on the Condor Connection.

    I would recommend it to anybody who needs this type of antenna.
