West, Toronto Ontario M3N1V7 Tel: 416-667-1000 [email protected] Obviously, an EFHW antenna has a "half-wave" length only at one specific frequency. This inductance has the effect of bring the resonances a bit. The Horizontal Loop, also known as the Loop Skywire Antenna, is an old but very effective design. The inverted v would also be a candidate configuration for an 80m antenna. And I’m going to keep this VERY simple. I bought this antenna (the longer one at 32m {105ft}) mainly to see how it would work in a space restricted property on 40m and 80m. 67 - Half-Sloper Antenna for 160m. 160m Linear Loaded Sloper Antenna. Whether you`re QRPbackpack, vacationing, emcomm station, or an antenna neighbors will never see, MFJs got an EFHW for you: MFJ-1982LP, $59. Below is one example of how to build an 80 metre band long wire antenna for a house with a smaller garden. Of course it is still very much QRP, and currently I am loading up my 40 metre end-fed dipole using 18 turns on an FT120-43 and my end-fed coupler which is just a terrible antenna for 80 metres so the actual radiated power is probably quite small. It works on 80/40/30/20/17/15/12 and 10 meter bands. Pacific Antenna SOTA Endfed Halfwave Tuner. is about one wavelength, so the impedance at the ends should be quite different from the impedance at the end on 80m. 20m, 17m, 15m, 12m, 10m, fed by a second coax. 08") Open the wire gauge and diameter calculator in a. 80m band is designed as an inverted L with a 19.

Posted date: March 29, 2020 in: Antenna. I don’t want to bring the radiating element in to the shack which will be on the first floor (second floor if you’re in the US!)) so I’m thinking of using a 9:1 unun with. Better yet, it worked, I made contacts on all bands. You can use a full-wave loop on frequencies higher. End Fed Vertical Antenna Variations. Above is the modelled gain for all three. The G7FEK antenna goes several stages further than the simple single band End Fed Zepp. I came across the following antenna which covers the 80-10m bands with no traps and just one loading coil. The following data are for the far field radiation patterns and 3D color views of an End Fed Half Wave Inverted-L antenna with a long, straight radiator at 40 feet and feed point straight down near ground. The 45 ft long End Fed is up about 20 feet and mostly horizontal. I wound 10 turns of the 14 gauge wire on a small piece of 1 inch O. 69 - Linear Loaded Sloper Antenna for 160m.

The antenna has a full 300kHz bandwidth on 80m between 3:1 SWR points. The ZS6BKW Multi-band HF Antenna April 7, 2017 This is the antenna for you guys who want to get on HF effectively and haven’t too much space or cash to throw around. Most END FED antennas on the market require a tuner, this one does not require one to operate. Above is a diagram from the ARRL Antenna Handbook (Silver 2011). 07mm stranded wire with an OD of 1mm. End Fed Inverted "L" Antenna Posted by YC1CWK - YUN at 4:40:00 PM. I've been making lots of A/B comparisons between this new EFHW against my ZS6BKW. One of the neat features of this type of EFHW coupler is that the antenna wire is DC grounded, so I simply made a ground wire to connect to another tent peg to drain the static off the kite line - 80m if wire in a stiff breeze will generate a LOT of volts that you don't want fed into your sensitive receiver front end!. Complete with 2 end insulators and 1 centre insulator; Resonates on 10m, 20m, 40m & 80m; Works on 30m, 17m, 15m, 12m, & 6m with antenna tuner; G5RV-300AC - true G5RV antenna - $109.
