40 meters 2 elements delta loop antenna Very unstable antenna depending by ground humidity ! In 2021 I simply could not replicate it even though same wires / poles and location used as before How to : 2020 : First build and test Why ? Having already a delta loop antenna in place, I wanted to see how a parasitic 2 elements array would perform.

Radiation Patterns. A full-size Delta Loop, fed in the bottom corner, is a good low angle radiator and is great for working DX. This antenna normally has about a 3 DB gain over a 1/2 wave center fed dipole. The Delta Loop is not only a great transmitting antenna but a low noise receiving antenna. The direction of fire is broadside to the antenna.

The Double Half Delta Loop (DHDL) was developed by George, AA7JV for his Lowband Expedition to Chesterfield (TX3A). It's a ground-independent Receiving antenna which only needs two 10m support poles. Once the wires are cut and the Balun build, it takes less than 20 minutes to deploy the antenna.

HF multiband Delta loop antenna
Delta loops require a full wavelength of wire (1005/frequency = feet or , for instance 1005/146.52 = 6.859) or approximately 6′ 10 7/8″ gives me the length of the entire wire. Since I will be building a 3-sided delta loop, I divide that 6.859 / 3 = 2.29 feet or about 27 1/2″ per side.

The Double Inverted HF Delta Loop Vertical A Skeleton Slot Vertical with Low-Angle Radiation, Azimuth Gain and Horizontal Polarization for Lower Noise Here is an excellent example of what a slot antenna can do on the HF bands. This design for me is one of the biggest payoffs of a three-year adventure with slot antennas.

Here is a simple and easy to build antenna in a Delta Loop configeration that should make 10 and 12 meters lots more fun if you have a limited space situation or you just like the idea of a smaller than normal sized Delta Loop. Gets lots of DX too and there is a simple modification using one boom and 2 Delta Loops for complete 360 degree coverage!

antennas mounted singularly (only one loop in the air). When mounting both antennas the SWR goes to 1:1 @ 3.8 MHz, just a little bit upper, due to the element's coupling. To phase the two loops, Dr. Ace WH2T suggested me to simply use quarter-wavelengths of 75-ohm coaxial cables feeds placed from any of the delta's feed-points simply to
