Sep 05, 2014 · Perhaps the biggest thing my station is missing is an 80m antenna. I really don’t have room for a full, half-wavelength dipole, so I’m looking for options. For a while, I used a W3EDP antenna, but to be honest, results were mediocre at best, and since the tuner I used was in the shack, there …

May 23, 2018 · It seems clear from this very basic, but perfectly reasonable, EZNEC simulation a full wave 160 meter loop running in the 80 meter band is a good antenna for DX work, but leaves much to be desired for NVIS even if you lower it towards the ground like you do with a dipole. Even at delta loop's maximum gain angle of 43 degrees, the delta loop has only 5.5 dBi gain. Compared to an inverted Vee dipole, or dipole, the delta loop lowers effective height of the antenna considerably, increasing wave angle; The more compact area of the triangular-shaped full wave loop further reduces the already small gain available from ...

WHY USE A FULL WAVE HORIZONTAL LOOP INSTEAD OF A DIPOLE ON 160, 80, 75, 60 and 40 METERS? (Rev 6/2017) A dipole antenna just will not work unless it is at a sufficient height.


So, I took the delta loop down, and converted it into a 1/2 wave 80m dipole, made the angle at the apex as near to 90° as possible (for a good impedence match), and hung it back up at 85'. NOW I have an antenna that really kicks some serious butt, locally as well as with DX.

Currently my ‘provisional’ 80m antenna experiment consists of TWO Phased 'Inverted' DELTA LOOPS, VERTICAL polarisation. Average Elements distance is about 63 degree. The average Antenna height is 13-14 m. Following the wise suggestions of Bob I1BAW I used VERTICAL POLARISATION feeding at the upper corners I just wanted to let you know that I built the KL7JR Sloping Vertical Delta Loop and I am having a great time with it. When I first built it, I fed it from the top (apex about 50 feet or so). After a week I decided to feed it from the corner. I have used it on most bands but my favorite is 20m.

Jim bakker show 2020Aug 28, 2015 · Several members of the Nashua Area Radio Club recently got together to help one of our members to put up a 40m Delta Loop antenna. Delta loop antennas are some of the best performing wire antennas and have the advantage that they can be easily supported via a single elevated mounting point such as a mast or a tall tree. Maybe the full wave delta loop can help? Delta loops are simple to construct and can look less intrusive than other antenna types. All you need are three mounting points, a balun, and some wire. Below is one example of how to mount a 20 metre delta loop on a small suburban house. This antenna is a high performance, full size, full wave, 80m loop antenna. A full wave loop, compressed in dimensions has much less than 1 dBd gain. That is hardly high performance, and the stub destroys harmonic resonances that are normally useful in loops. On 40m it is a 2 wave length open loop or Bi-Square.

Even at delta loop's maximum gain angle of 43 degrees, the delta loop has only 5.5 dBi gain. Compared to an inverted Vee dipole, or dipole, the delta loop lowers effective height of the antenna considerably, increasing wave angle; The more compact area of the triangular-shaped full wave loop further reduces the already small gain available from ...

I recently had great results with a delta loop on 10 meters and a rectangular loop on 20 meters, (50+ countries in 3 weeks of casual operating!), then I decided to take the plunge and put up a 80 meter full-wave horizontal loop which would allow operation on all HF bands.

However, you may find that your mono band delta loop may tune up on it's second harmonic at a higher frequency eg. 160 m loop on 80, 80 m loop on 40, 20 m loop on 10, etc. My SWR testing on the second harmonics showed RF and SWR needles swinging up and down together which usually isn't a good indication of an efficient antenna. 61 – Tri-band Delta Loop Antenna for 80m – 40m – 30m. 62 – Dual-band Loop Antenna for 30m – 40m. 63 – Wire-Beam Antenna for 80m. 64 – Dual-Band Sloper ...

Jan 08, 2012 · Antenna experiment - Delta Loop for 7 Mhz band I had a 80 m dipole that was not performing too well because it was only at 25 ft height due to physical constraints in my backyard. Looking at my options I decided to re-use the antenna materials and make a delta loop for 7 Mhz band.

This had 4 x 2 inch coils in each corner of the loop with 30 turns of 1mm wire and I stretched the loop all around the garden and even inside the attic to make the loop as big as I could. I estimate this was around 60m in circumference.
