  1. The antenna costs almost nothing to construct and should handle up to 50 Watts of power. The antenna is broad-banded and should therefore provide a low SWR across the entire 2-meter band. A J-Pole antenna is a half-wave vertical fed at its base through a shorted quarter-wave stub acting as a transformer matching section
  2. I decided it was time to set up a 2 Meter base station. Being the crafty maker type, I wanted to build my own antenna. I settled on a 2 meter vertical dipole. I proceeded to make a very heavy dipole from copper pipe, akin to the type used for J-poles. It was incredibly heavy and very quickly became a sagging and corroded eyesore on the corner.

You get an improved 300 Watt 1/4 wave ground plane for 2 Meters thatll bring up repeaters as well also r better than any 1/4 wave ground plane -- even if they cost twice as much. The improved MFJ 1/4 wave ground plane minimizes feedline radiation for more useful radiated power, reduced TVI and noise pickup by the coax shield 9,051. Sep 14, 2020. #25. Well I've had my new REMTRONIX VHF/UHF 2m/70cm antenna for a couple weeks now. So far it's about what I expected. If I had to guess it might be performing a little better on VHF than the Diamond RH77CA. It should be noted I'm using it for the VHF airband, not VHF amateur radio

2M Band Vertical Base / Repeater AntennaSpecial Features: Heavy-duty aluminum antenna sections Encapsulated matching network for weather protection Stainless steel mounting hardware and radials Factory tuned, no adjustments requiredSpecifications Other than that, this antenna acts just like the classic center-fed dipole. Again, because it is a half-wave antenna, it does not need a ground plane. Fully extended, the antenna is 42 inches long but it collapses down for storage (Figure 2). The MFJ-1714 costs less than $20 and comes with a BNC connector I bought this antenna right after I bought my VX7R. Over the last few weeks I got tired of the size and weight of the antenna so I tried to replace it with the Diamond SRH77CA Dual Band (2 m /70 CM) HT Antenna. Let me give me your a brief overview of how the AL-800 performed 27 pf at 2 meters is ~40 ohms reactance so it's a sane value for some sort of match, at least. e: yeah if you take a 49cm whip against perfect ground and lengthen it to about 53, 54 cm, it comes up to 45-50 ohms resistance +j40 ohms. a 27pf cap would tune that right out and make it dead flat on 2m. up on 70cm the cap is only 13 ohms of. Bill4 mentioned amount of antenna movement in the wind. Yes they do! It has made me winch more then once. I check it about every two years and no cracks noted. Not a fan of the little phillips set screws but they are tight when inspected. If you happen to listen outside of 2 meter/440, you should be impressed with the usable frequency range

There are times when you may need more gain than the standard J-Pole antenna. With twice the gain of a standard J-Pole antenna, the 2 meter Slim Jim antenna is a J-Pole on steroids! The Slim is an end-fed folded dipole antenna that has a gain of 6 dbi and a nice low RF take off angle. This makes the 2 Meter Slim Jim antenna a great solution for repeater sites, data and packet stations, APRS. Arrow Antennas Portable Satellite Yagi Jpole 2m 6m.

To work efficiently the short mobile antenna must be resonant. 2. At the resonant frequency F0 the antenna generates the maximum voltage across the antenna and the maximum current through it, with the correct phase relationship. Efficiency drops rapidly as you move away from the resonant frequency. 3 Here are the plans to build a 2 meter J-pole antenna: The above dimensions for the J-pole are in inches. Measurements on overall length, and stub length are from the centerline of the separation pipe (horizontal) to the top of the antenna. The Connect at measurement is 2 1/4 inches from the top of the horizontal member to the point of connection

The antenna site elevation is approximately 13 m AMSL and is about 200 m from the shore of Cook Inlet. The antenna uses a pipe mount as shown in the pictures.

It is a 1/4 wave on 2 meters providing 2.15 dBi gain and a 1/2 wave on 440 providing 2.15 dB gain. This antenna can handle up to 100 watts. VSWR is less than 1.5:1 The 2-meter roll-up J-pole is lightweight (approx. 3 ounces), compact and effective! The antenna can be set up quickly and easily by hanging out a window, attach to a ceiling, or toss a lead sinker over a tree branch with kite string and hoist it up. Slide it inside PVC pipe for rigid vertical installation (retuning required) I debated between and finally chose the 1/4 wave antenna instead of the higher-gain MFJ-1728 for two reasons. 1, I didn't want the taller antenna hitting the garage door, and 2, the 1/4 wave covers 70cm instead of 6 meters. I have a dual-band 2 meter/440 HT, and I'm unlikely to ever need 6 meters

2 Meter 440 Vertical Collinear Antenna Project by W7LPNPin on HAM Radio n electronic

Assembled 2 metre cubical quad antenna. The boom for the antenna is made out of two lengths of 25 x 25 mm wood. If necessary the spacing of the parasitic elements can be adjusted with these two lengths of wood acting as a clamp. However once all the adjustments have been made then all the elements should be firmly screwed and glued to the boom There are 2 ways you can co-phase antennas. You can buy a power divider or you can do the T connector method as I did w/my own stacked 5's. Co-phased system using a T connector: If you choose to do the T connector method, you will have get a T connector where all 3 ends are female. You will also have to make a co. ARRL, R. Deam Straw.

Wire Antenna Modelling with NEC-2. Antenna Engineer 8/12/2009. PDF (Sept 2011) Daniel C Lester (KE9SE) This page documents a build of a 2-element 1/2 wave collinear J-Pole performed by Harry, KC9EOT, and myself, KB8OJH. We fabricated two identical J-Poles using the dimensions in this document, and both of them performed quite well, with a resonant frequency toward the lower end of the 2-meter Amateur band and a VSWR of 1.5:1 or better over the entire band This antenna is a 1/2 wave vertical dipole made out of RG-58/U coax. The beauty of this design is that it is cheap, simple, and easy to make with readily available materials. The radiator should be 39 inches long for 2 meter operation. What I use for the radiator, is the center conductor of the RG-58/U coax. I start out with a 12 foot piece of.
