      The coupler is a tuned impedance transformer, not an antenna 'tuning' unit. Stick to the above, and it should be a sure thing! Feeding a 21MHz half wave. A half wave vertical for 21MHz. 6.65 metres of wire on a 9 metre fibreglass pole. The coupler is mounted 2 metres up and attached to the top of the fence. My antenna is a Chameleon Lightweight End Fed Sloper . I have never had the slightest problem with RF in the shack with normal SSB phone use. 80m half sloper antenna. This is post 2533 in a continuing series of simple ham radio antennas. According to Kevin Loughin (KB9RLW), you can learn a lot about antennas with some simple experiments. In this video, Kevin compares the performance of an end fed halfwave sloper antenna with a conventional flat horizontal dipole antenna. The Sloper Antenna Explained. The classic sloper antenna is a top-fed 1/4 wave vertical antenna sloping down and away from a tower. The sloper's feed point is anchored high above ground near the top of the tower on which sits a grounded HF yagi beam antenna. The yagi plays the role of a ground plane, while the tower plays the double role of .... Jan 12, 2017 · Eighty meter amateur radio antennas tend to be large, with a half wavelength dipole approximately 135-feet/41.15 meters long. A shortened 80 meter sloper antenna may be what you need for a small urban lot or for portable operations. This video from "AmericanRadioSupplies" features an 80 meter sloper antenna designed and built by W8AMZ.. Feb 08, 2019 · On the inside of the pipe measure the wire to the second hole and make a notch/fold here. Pull the wire out straight, cut it and scrape the enamel off. Fit a crimp and again line the ring up with the hole and push a screw through, fixing with a nut. This coil will act as an inductive load for 80m and a trap for 40m.. I have mounted a 75 ft long 80m half sloper from it at about the 72 ft level. It comes off the tower at about a 45 deg angle, and ends about 20ft above ground. ... 80 & 75m with one sloper. It is a noisy antenna for receive, and a year ago I added a set of K9AY loops for a low noise Rx antenna. My country count currently stands at (worked.

In this video, Kevin compares the performance of an end fed halfwave sloper antenna with a conventional flat horizontal dipole antenna. MFJ-1984MP, END FED, 1/2 WAVE, 40-10M, 300W, WIRE ANTENNA. Description. FULL HF Coverage, no tuner needed on most frequencies. No long counterpoise, radials or feedline required. Rugged weather-resistant 50-Ohm matching network. Fast Setup and takedown.. EFHW-4010-1K-Plus™ Multi-Band End Fed Half Wave Antenna. This is an End-Fed Half-Wave (EFHW*) antenna for 40/20/15 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. It is a resonant Half wave on 40m (7MHz) therefore also resonant on second, third, and fourth harmonics. Sloper with a 50·,Q line. The result is a broadband, 10w·Q antenna (Figure 3). Don't think of this as just one antenna, but rather a whole family of antennas, one for each half wavelength of added length. Technical Concepts If you just want to build an antenna, skip ahead to the Practical Antennas discussion. Those with a technical.

    • EndFedZ® Overview. The Par End-Fedz ® are a full length half wave dipoles, but with an important difference. The coax connector is at one end of the dipole, where it is most needed. These antennas can be mounted horizontally, vertically or as a sloper. No ground plane or counterpoise is needed. Portable operation could not be easier.
    • Here we take a look at an End Fed Half Wave antenna which is resonant on many HF bands due to a 49:1 matching unit being used.Antenna Design Plans: http://ww.... At the same time as I added the 80M half-sloper, I added their 160M, 60M, and 40M standard double-bazooka antennas. Since all 5 antennas are mounted on one tower, positioning and tuning was not cut and dry but thanks to David's knowledge and willingness to help, after several emails with pics and phone conversations with him, they are all .... 2008-12-01. Great small 160 antenna. Time Owned: 3 to 6 months. I recently installed this sloper with the upper end at 35ft and the lower end at 8 ft of of my 40ft Rohn tower. Also installed a dedicated ground wire from the antenna to 3 8ft ground rods. I have made many contacts at 100 watts with very good results.
    • This shortened 80m sloper is an ideal compromise antenna to get you active on 80m.Do you want decent performance on 80 meters?If you have 25' of height you c. The antenna is fed with open wire half way the vertical part on the left (red circle). The bottom part of the antenna is at 3 meters and 30 cm's above a flat roof. The most right of the bottom wire is attached to the house (using insulators). The cross is the 80 meter coax trap. The top is 23 meters high and goes to the right to a pole on the. W8AMZ 80M ½ Sloper Kits are designed to handle up to 1kW SSB maximum. W8AMZ 80M ½ Sloper Kits require fine tuning to achieve best SWR. The W8AMZ Dipole Antenna Kit is proudly made in the USA Even more so, all except two components of this antenna are USA manufactured. 231-855-0281. www.w8amz.com. The ULTIMAX-8040 broadband dual band. The physical length of any HF antenna is critical to achieving resonance and good performance on a particular band. Dipoles need to be half a wavelength long, locating these long antennas can be an issue, especially when we are aiming for the 80 metre band or lower. However, we can reduce the space needed to a quarter wavelength if we decide to. SLOPER ANTENNAS . TZ-SL8 $ 99.00. Half sloper for 80m (requires tower) TZ-SL16 $ 119.00.
