N9ZRT Kite-Lifted Antennas
- Kite-lifted wire winch consists of 1/4 mile of 15 gauge, bare, solid, aluminum wire, spooled onto a wide pneumatic hose reel. The base pivot-platform locks into place for changing wind direction.
NVI 40 Meter Antenna Modeling
- The idea of using a low mount dipole, enhanced with reflector wires directly beneath the dipole, on the ground, appears to be a very good approach to creating an NVI specific antenna for local HF operation.

K0RWU Multiband dipole 6-17 meters
- This antenna consists of 4 resonate dipoles made from 12 insulated copper electrical wire. The dipoles are resonate on the following bands: 6 meters, 10 meters, 12 meters and 17 meters.
Do-It-Yourself Wireless Antennas
- Your guide to wireless antennas, how to build a wireless antenna without spending much money
The Pringles Cantenna, Coffee Can Antenna, Parabolic Reflector and Antenna Designs. Combine a homemade Tripod Mount with an inexpensive Pistol Grip and go Wardriving.
Windom Antenna with 4:1 balun
- The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
WPI Wireless Association
- The Worcester Polytechnic Institute Wireless Association has its roots in the beginnings of Amateur Radio. The group was first founded in October of 1909, by Oliver B. Jacobs and a group of 40 other men.
The ElectraSlide Antenna
- Modification of the DK3 design by Don Johnson, W6AAQ. No voltage dropping, operates on the full 12 volts. The control switch and the matching toroid are supplied. All you need is a standard 3/8 by 24 thread ballmount, 2 wire sheilded microphone cable for control wiring, and a CB whip cut to resonance.
3 EL Quad Designer
- This DOS program will figure the wire sizes for a 3 element quad and will also give you the distance from the center of the boom to drill your holes for mounting the wire on the spider. it also gives you the length of the 4 quarter wave lengths of wire in case you would like to figure the spreader drill points yourself.
