J-Pole Antennas for 2 Meters  ^pop - This paper describes two types of 2 meter J-Pole antennas, one made of copper pipe and a roll-up J-pole made of TV twin lead. The figures give the details of the dimensions, components and construction.

A Feasible Full Sized 40 Meter Beam - This project started as a result of renewed interest in 40 meters coupled with the desire for an antenna system that would be more effective than the simple dipole.

My 80 Meter Magnetic Loop  ^pop - A custom made 80 meter loop antenna. Reports on usage and tips to build the support.

SM5DCO EH antennas - The Swedish EH Antenna Group

The G5RV patterns - G5RV detailed antenna patterns and 3D plots setting it up as inverted V with a different angle, compared to horizontal way.

Super J-Pole plans - The super J-pole is a regular J-pole antenna with a 1/2 wave element mounted above with a 1/2 wave phasing harness connecting the element to the bottom part of the J-pole. The antenna can be built for any band, but I built mine for 2 meters

Easy J-pole antenna  ^pop - Everybody says keep one in your bag, nobody seems to make one work right. Here's the straight scoop on why the J-pole is not an easy antenna to duplicate!

Cebik Moxon Rectangles - The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.

W6NL 40m Moxon Yagi - Designed and built by W6NL looks like a loaded yagi this 2 element moxon antenna offer 6dbi

Rotatable delta loop - W2UP rotatable low band receiving delta loop

Young Amateur Radio Operators Club (YAROC) - Bedfordshire and Hertfordshire, UK-based group for young radio amateurs. Includes club information, online registration, guestbook and links.

W4ATC Student Amateur Radio Society - The NCSU Student Amateur Radio Society (W4ATC StARS) is a group of men and women who practice the hobby ofamateur radio. We represent a wide range demographics, of majors, and of interests.

Yahoo! Groups : eh-antenna - This group has been created to promote discussion relating to the EH Antenna. There should be many with experience with the EH Antenna, so don't be shy about asking questions on construction and efficiency.

MorseMad - There are pages with info on the code, pictures of morse keys, a couple of downloadable tutor programs, mystery keys etc.

Southern California Repeater Lists - The most up-to-date listing of VHF/UHF amateur repeater stations operating in Southern California.

Automatic Picture Transmission - Automatic Picture Transmission (APT) is used by Satellites to enable a fully automated unattended reception of the transmitted pictures.

PC to RTX interface - Schematics for IC-706, IC-718, IC-756PRO, TS-570, TS-870, and simple universal S.B. interface All three interfaces presented on this page employ galvanic isolation of the transceiver from PC computer. Audio paths are separated by transformers, optocouplers serve to separate the digital paths (PTT and RTTY keying).
