80 Meter Delta Loop Saves The Day - eHam.net
I had played with the delta loop a bit before the wreck but now that it is my only antenna I checked it out further. Here are the results. 160 meters It will load using my manual tuner 80 Meters 2:1 3681-3933 Khz 40 Meters 2:1 7127-7300 20 Meters Requires tuner 17 Meters 2:1 entire band 15 Meters 2:1 21000-21.245 12 Meters 2:1 entire band
Reviews For: Alpha Delta DX-LB (shorty) dipole for 160-80-4
Mine is for CW, and 160m is narrow-banded but I dialed it in well enough to work the WAS net and the ARRL 160m contest. Regional contacts were easy. Russia called me on the net, but I couldn't hear it. 80m is better, it is possible to work powerhouse DX stations with my AL-80B. West Coast from here in Dayton is iffy.

Superb, easy, effective loop antenna Time Owned: more than 12 months. June 19, 2016 I received and installed this interesting loop and balun (40-20-10 meter version) about two years ago. In brief, it is a wonderful performer even at only 30 feet high.

My Alpha-Delta DX LB Plus is mounted as an Inverted V, 50' at the apex with each foot @ 20' above ground. Antenna analyzer shows 47-53 ohms, depending on which band I'm on. If you're considering buying the Alpha-Delta DX LB Plus, consider the "fixes" I describe above to extend its life before you hoist it into the air.
Getting on 160 Meters on a Budget - eHam.net
___The smallest successful , easy to build 160M antenna I've built is a 3/8 wave loop. The circumference is about 200 ft of RG58 (using the braid as the antenna conductor to lessen copper losses). The loop requires a couple of trees about 50' to 70' apart. The idea is to make a 50' by 50' square if you can, but my loop was a rectangle 70'W by 30'H.

I also could do some SWL on the CQ WW 160M contest, and again could ear some US stations getting through the huge QRN. About the installation, the metal plate of where the coaxial is being attached is @ 7meter high (23 feet) above the top of the building. The 160M leg of this antenna has 60 feet or 18 meter.
An All Band Loop - eHam.net
A good loop antenna has always been on my bucket list -- I thought I had enough room at my present QTH but I am about 50-75 feet short of room for an 80 meter loop -- and it would look like a sideways delta. If I run a loop, I don't wanna use a …

I bought the delta loop at a radio rally last year, but only briefly tried it out. Today I set it up and connected it to a MiniVNA-Pro analyser. Over the HF band the SWR was always above 5. Once into the VHF region the SWR pattern "stabilised" (the graph plot oscillated up and down repeatedly) and there was a SWR of 1 at 140MHz.
Delta RX Antenna used by FO0AAA - eHam.net
The Delta is a modification ofthe "delta-shaped Ewe loop" shown in figure 7-66 on page 7-51 of ON4UN'snew Low-Band DXing book. I took John's Delta-Ewe and, with the feedpoint and termination locatedat the bottom corners of the triangle, I used EZNEC to optimize thedesign for best F/B and zero reactance at 1.830 mHz.
