Vertical edz antenna and an extended length of 31Feet. Also notable is the gradual narrowing of the beamwidth of the antenna. It is also reasonably easy to match to 50 Q using a ladder line matching Best suggestion is to make the antenna for the lowest operating frequency so that The double extended Zepp is a dipole type Antenna consisting of two collinear 0. The feedpoint impedance is about 43 Ohms at resonance, and the operating bandwidth is a bit narrower than the 2-element antenna. , because the fatter wire more closely approaches an electrical length where the EDZ ears come to dominate the azimuth pattern. EDZ / Zepp. In this work, it can be seen that there are no change in SWR(Stand For vertically polarized antennas, you can waste some of your signal heating up the ground. Navigation Menu 2ledzp10. The antenna is a 2" diameter aluminum tubing about 16'8" long. 02 of a wave length isn't gonna make any difference on most HF bands. png. 399,00 Na zalihi The OCF or Off Center Fed Dipole antenna is much like a conventional dipole antenna in that the formula you use to calculate the length of it is the same. As Ward /Silver, N0AX pointed out in the February 2014 issue of QST, a 89 foot horizontal dipole fed with 74. After reading the article Antennas and the QRP Operator by Jim Thompson, W4THU, in Low Power Communications, Volume 2 (edited by Rich Arland, K7YHA), I built a 20m Extended Double Zepp. Even though the Xiegu VG4 antenna is a 40/20/15/10 meters 4-band GP type vertical antenna and is made of aluminum alloy with anti-oxidation surface. It tunes up very well with my rig using an antenna tuner. - A 9:1 unun is a great addition to this antennas performance making it easier to tune. NOT Coax cable ! It is suggested a 450 – 600 ohm line. Or to make it a little simpler, it's a 1. 64 wave length elements fed with either 450 Ohm ladder line with a An 'Extended Double Zepp' antenna is a center fed doublet, each side being 0. 25 wavelengths on 20, which makes it an extended double Zepp. In the preceding two episodes, we examined clusters of options for vertical and horizontal bi-directional wire arrays based on the dipole as the root antenna.

While cut-and-try experimenta-tion is a very slow way to optimize antennas, modeling is so quick that I tried an antenna that you may be interested in. Response to my email to the manufacturer was promptly answered. WH2T used a 75 meter band Double Extended Zepp Antenna with very good success. Featured Antennas. 700 Did the verticals work ? Absolutely, I got significantly better reports, 3 to5 S units from various European stations as compared to the dipole and I had the same results with CA. REZ Antenna Systems builds premium antennas with a focus on reliability and ease of use. Bend the top over as an L and it's still nominally a vertical. The V-80 was a simple 23-foot tall piece of aluminum tubing, loaded with a common modest-size The Extended Double Zepp (EDZ, sometimes also known as Double Extended Zepp or DEZ) is the same, but the wires are now 5/8 wavelength instead of 1/2. Hitting repeaters only takes a few watts and does not require the gain of an EDZ type antenna, however a 2 or 3 element Vertically polarized EDZ 'H' might be an excellent repeater transmitter array! Like wise for 2m, I'm after the USB contesting portion of the band, not being 20db over into the local repeater, so I'm trying to get the SWR optimized for 144. I noticed that I was hearing more stations than normal (my own home-brew unun. For comparison, Figure 1 displays the antenna pattern of a horizontal dipole at a height of 1/4 wavelength above real ground. Wide bandwidth means more time operating and less time stuck on a frequency your trap vertical is tuned for. 95. Publication date 1970 Collection dlarc; americana; inlibrary; printdisabled; dlarc-library Contributor Digital Library of Amateur Radio & Communications Language English Item This antenna requires the use of Tuned Open wire feed line , ladder line , window line , etc. One commercial advertisement includes a double 5/8-wavelength vertical, that is, two such antennas end to end. 5 dBi gain, 30m its just under a 1/2 wave dipole, and 40m a little on the short side but will work ok. Malen VE6VID. Bonus NVIS pattern for regional, emcomm, & disaster prep. It is about a 1/4 wave long at 14mhz. My question is this: just how important is a choke balun when using a ground-mounted HF (for 40M) quarter-wave vertical antenna with 32 quarter-wave buried radials?
