The RockLoop Antenna is a compact multiband portable and indoor antenna suitable for QRP operations on the 10, 14, and 21 MHz bands. The page provides detailed information on the design and usage of this antenna, making it a valuable resource for amateur radio operators looking to improve their setup. The intended audience is amateur radio operators interested in building and using antennas for QRP indoor operations. -
The W5GI Mystery Antenna is a multi-band wire antenna that covers 80 to 6 meters with low feed point impedance. It is easy and inexpensive to build, similar to a G5RV but performs better on 20 meters. The antenna is difficult to model but has received positive feedback from users worldwide. It is ideal for hams without towers, requiring only two vertical supports about 130 feet apart. The antenna consists of three half waves in-phase on 20 meters with a half-wave 20 meter line transformer, offering a six-lobe pattern, gain broadside to the antenna, and low feed point impedance for easy matching. -

An effective 10-20m DX antenna for deed restricted lots. The article by K7ZB introduces a simple 10-20m DX antenna suitable for deed-restricted lots. The antenna, a 15' vertical design, facilitated contacts with over 200 countries worldwide. Its design employs a telescopic aluminum tube and radial wires for multi-band operation, requiring an external antenna tuner for optimal performance. The mounting scheme and construction details ensure effectiveness and ease of use. -
The page provides guidance on building a mobile antenna for HF bands using a cheap CB-mobile whip antenna base. It discusses the importance of high efficiency antenna systems with a slim profile for low wind resistance, along with physical constraints and design considerations. The author shares instructions, tips on mounting the antenna, grounding, and band switching. The page includes a graphic illustrating the antenna's principle of operation and a table with reference lengths for different bands. -

A 10-20 meters coverage delta loop antenna. After relocating, DL2HCB designed a multiband loop antenna to cover 10-20m with an open-wire feed for impedance matching and compact installation. Inspired by the mini-X-Q design, a modified 10m delta-loop was built, enhanced with a 1/4 wave shorted stub for 28 MHz using 450-ohm ladder line. The antenna delivers east-west broadside radiation and performs as a closed loop on other bands. Operational tests yielded strong European signals and successful DX contacts, including a 20m QRP QSO with FY/DJ0PJ. -
The Petlowany Three-Band Burner is a simple, low-cost, trapless short vertical antenna which amazingly works on three HF bands (20, 15 and 10 meters). This web page contains pictures, performance data, and enough construction details so you can homebrew your own. -
This loop it is small and light enough to carry while operating, it disassembles into small but rugged pieces that fit easily in a backpack or gym bag, and it can be tuned from 14 MHz to 30 MHz. This tunable magnetic loop antenna is my contribution to the well established art of amateur loop making. Can be tuned from 14 MHz to 30 MHz. -
A simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres, made from 16 feet of RG58 coax cable. The performance is impressive for its size but not meant to replace a Yagi. The antenna features a tuning head, matching unit, tuning capacitors, band change switch, and matching transformer. The feedpoint is at the bottom of the loop. The document provides detailed instructions on assembly and operation. -

The antenna I built was inspired by a portable delta loop designed by Doug DeMaw, W1FB. Given that I constrained myself to a 50-foot roll of speak wire, I scaled my antenna for the 20M band. Using the formula, 1005 divided by the frequency in megahertz, I calculated a total length of 71 feet (21.6 meters) for the center of the 20M band. -
