A second product line called the Buddistick contains pieces for a single element for vertical antennas only. Buddistick systems are less expensive than the Buddipole systems since they contain fewer parts. Specifically, the standard Buddistick system contains • One coil • Two 11 inch aluminum arms • One standard whip (5.5 feet) • Two coil clips • Mounting plate with knob to mount plate on a standard ¼"x20 photo tripod or similar platform. • One 31 foot radial line on a winder with ring connector • Attaché style carry bag Buddistick system The Buddistick is a subset of the Buddipole except for the mounting plate and radial line. The typical deployment for this antenna is tabletop or 17
picnic table with a clamp securing either the mounting plate or the antenna directly. A very handy third-party mount for this antenna is sold by High Sierra. (www.hamcq.com) It is called the Jaws Antenna Mount. The mount combines a very strong clamp with a standard 3 / 8 "x24 mount that works with all Buddipole and Buddistick components. The clamp will grip wood (2x2 or 2x4 in size), railings on hotel balconies, fence posts, or nearly any other object. The piece holding the 3 / 8 "x24 mount rotates 90 degrees to allow the position of the antenna High Sierra JAWS mount to be independent of the angle of the clamp. It is heavy duty (and heavy!), and holds an antenna firmly. The antenna is fed from an SO-239 connector on the bottom of the antenna mount. The next step up in the Buddistick product line is the Buddistick Deluxe Package which includes everything in the standard Buddistick pack plus an extra whip, extra coil clip, and a lightweight vertical antenna clamp for picnic table use. It is not as rugged as the High Sierra offering, but it is much easier to pack and travel, and it works fine for light duty situations such as a casual picnic table portable operation. The Buddipole and Buddistick systems may be augmented by any of the accessories in the Buddipole, Inc. catalog. The next few pages highlight some of these accessories. Some, such as the Triple Ratio Switch Balun (TRSB) and Low Band Coil, will be given additional coverage later in the book. The Triple Ratio Switch Balun (TRSB device serves two purposes. It has a threeposition switch that selects either 50:50, 50:25, or 50:12.5 ohm matching from the feed line to the antenna. The TRSB also has an isolation transformer to keep current off the outside of the coax. The TRSB was developed by Alan Biocca, WB6ZQZ, for Buddipole, Inc. 18
