"N6 Bravo Tango, this is N0 Papa Golf. Tony, Iowa, number 69591." I made it with one call: February 5th, 2000, my first contact with "The Illuminator." KB9TQI, Indiana; N0IJ, Minnesota; K4CIH, Alabama; WA9TPQ, Illinois; N5MT, Texas; KB0MZG, Kansas; and, KX9DX, Illinois were other contacts made in the 10/10 Contest, slipping into the radio room from time to time while working in the yard. The path to Indiana was the farthest on record for me with the 150-W light bulb perched on a fence post. What a pleasant surprise, and there was more to come.

Flags and Pennants – Introduction by K6SEI’ve been getting a lot of e-mail asking about “the published article” on the Pennant and Flag receiving antennas. I get the impression that a rumor has been circulated that an article has be published about the Pennant. Rather than answer each individual query, a posting on the Topband reflector might be better. There never
Short towers near tall treesMany years ago I was experimenting with a two element 40 meter phased array. It was composed of two quarter wavelength vertical radiators with moderately good ground systems, spaced a half wavelength apart, in my back yard. The radiators and ground systems were, as close as I could make them, identical. A friend made some
Notes on ground systemsIs it permissable to have both elevated and ground radials? Yes. But with only a few radials (less than about 8 radials per antenna) any radials contacting or very near earth will reduce system efficiency. Does a ground rod at the juncture of the radials hurt or hinder? With less than about 8 elevated radials,
My Bad Experience with Commercial AntennasHams living within cities and urban lots are often unable to erect a tower with a regular Yagi or Quad. Experiments with wires may require a lot of space so many Hams “ending” with a multiband vertical antenna. Regardless of wide availability of many types of such antennas the answer to the question “what antenna
Double Half-Delta Loop RX Antennaby George Wallner, AA7JV This antenna was developed to meet the need by the TX3A Chesterfield DXpedition for a small, low-band, ground independent directional RX antenna that only requires two support poles. The antenna can provide reasonable performance for the space limited amateur, as it fist into a 60 x 60 foot back-yard. Smaller version
