Click to enlarge2 Meter Hentenna by WAŘITP
I thought I'd drop a note about my experiences with the Hentenna. I just built a 2 Meter version of it out of 1/2" copper pipe. It was 39" x 13", a nice workable size for a gain antenna.

Here are the building instructions on the 2 meter square loop. Credit is given to K0FF for most of this design. We have added modifications that proved useful in the design.

This is a vertically polarized Broadside and Collinear Array each Loop is a vertically polarized Broadside Array both the right and the left side of the Loop is a bent 1/2 wave dipole working 180 degrees out of phase with the other one and that gives you 4.15dbi of gain.

Een artikel in electron van PA0PEV over een 6 meter deltaloop antenne bracht mij op het idee om een deltaloop voor 2 meter en 70 cm te maken.

Click to enlargeThe "Slingshot" Antenna for 2 Meters by N4UJW
The completed antenna is bi-directional with a rough figure 8 pattern and is composed of 2, 3/4 wavelength sections of electrical conduit bent and cut to the lengths on the picture below.

From time to time we have written about the small transmitting loop antenna, sometimes called the magnetic loop because its radiation is generated only from its magnetic field (and not any electric field).

VHF Magnetic Loop by ON6MU
A magnetic loop has a very small bandwidth but unsensitive to man made noise. It is much smaller then a conventional antenna for the same frequency and has a gain that can be compared to a quarter wave antenna.
