• ZR6KMD 2M Beam Antenna - This design was adapted from an article in the ARRL Handbook and built with simplicity and duplicity in mind. This antenna is a vast improvement over a standard dipole with a forward gain of around 8db with a front to back ratio of 10db.

• 40-80 Half-Extended Double Zepp Antenna - A dual-bander for 80M and 40m. An Extended Double Zepp (EDZ) is a 5/4 wavelength center-fed dipole. This article will introduce the Half-Extended Double Zepp (HEDZ) which has characteristics that a lot of amateur radio operators should find quite interesting

• A Stealthy 75 meter antenna - The 75 meter dipole at K7ZB was put up to meet the need for making contacts with friends in the Southwest and Southern California. As usual, it had to be put up so no one can see it from the surrounding neighborhood.

• A 5 band log periodic dipole array - Modified version of the Telerana antenna which was orginially featured in the July 1979 issue of QST. The array is suspended within a framework made of fiberglass poles emanating from a central hub with the ends tied together with light weight rope around the perimeter. 10-15-20-30-40 meter band coverage
