Berne, becoming a surgeon. He was also a researcher and a professor at USC. He was noted as a pioneer in the field of kidney transplantation and was widely respected and loved by many. However he chose to be just Tom to his many ham radio friends. In his teens, he had discovered his affinity for amateur radio and pursued it happily for the rest of his life. It was his nature to share experience he found fulfillment in. He was especially motivated to reach out to younger people, guiding them ever so patiently and gently. Tom was a member of the Pasadena Radio Club for many years, sometimes as a club officer, taking an active role in contests, field days, and other events. As always, he was supported by his beloved wife Cynthia. In the fall of 2007 Peter Fogg, KA6RJF, then club president-elect, suggested that Tom might consider writing a column for the monthly newsletter, The Pasadena Radio Club Bulletin, especially for our club’s technicians, to encourage upgrading and for new generals, to help them build HF equipped shacks. Tom was modest about his experience, but Peter persuaded him to create the Crown City HF column, which he wrote every month for eight years. Ten months after the column ended, Tom became a Silent Key at age 81. We were all blessed to have had Tom with us for those many years. Since then, Bob Ross, WA6JLP, volunteered to collect Tom’s work in a single document. We are pleased to present for you that collection of all of the Crown City HF columns. John Minger AC6VV Editor - The Pasadena Radio Club Bulletin, Past President - Pasadena Radio Club Crown City HF aspects, many of which differ significantly from VHF and UHF.

  • ZS6BKW Vs G5RV Antenna
    ZZS6BS6BKWKW vsvs G5RG5RVV Antenna Patterns/SWR at 40 ft Center height, 27 ft end height ~148 Degree Included Angle Compiled By: Larry James LeBlanc 2010 For the AARA Ham Radio Club Note: All graphs computed using MMANA GAL http://mmhamsoft.amateur-radio.ca/mmana/index.htm ZSZS6BK6BKWW // G5RVG5RV WhaWhatt isis it?it? In the mid-1980s, Brian Austin (ZS6BKW) ran computer analysis to develop an antenna System that, for the maximum number of HF bands possible, would permit a low Standing Wave Ratio (SWR) without antenna tuner to interface with a 50-Ohm coaxial cable as the main feed line. He identified a range of lengths which, when combined with a matching ladder line length, would provide this characteristic. According to an acknowledged expert in computer antenna design and modeling, L. B. Cebik: “Of all the G5RV antenna system cousins, the ZS6BKW antenna system has come closest to achieving the goal that is part of the G5RV mythology: a multi-band HF antenna consisting of a single wire and simple matching system to cover as many of the amateur HF bands as possible.” Both are “good” antennas and will work well in defined situations. This presentation is not designed to “bash” the G5RV, but to possibly convince you or a new ham to enjoy the benefits of lower SWR, lower loss, and greater signal strength by using the ZS6BKW version of a ladder line fed dipole. ZZSS66BBKWKW // GG55RRVV WWhhyy II liklikee itit 1. Has low swr in several ham bands at the matching point at the end of the ladder line resulting in lower losses in the coax cable.

The lower ends of the two lines should be stripped and bent over and soldered together. The resultant active line length must be 13ft. The dis- tance from the centre insulator to the ladder line should be 17.5ft. If you have a lot of wind in your area you might want to tie a 1oz lead fishing sinker to the bottom of each of the phasing lines. Alternately a string can be attached and tied to some secure point below the antenna.

  • The G5RV Antenna System Re-Visited the G5RV Antenna System Re-Visited Part 1: the G5RV on 20 Meters
    The G5RV Antenna System Re-Visited The G5RV Antenna System Re-Visited Part 1: The G5RV on 20 meters L. B. Cebik, W4RNL Louis Varney's "G5RV" was and is not an antenna, that is, an array of elements. It is an antenna system including a radiating element and a length of transmission line designed to present a "correct" impedance at a design frequency. The 1984 RADCOM Version of the Antenna System The most familiar part of the system is the wire: a center-fed doublet 102' long. Actually, Varney calculated the length to be 3/2 wavelengths long at 14.15 MHz using a long standing equation: The letter 'n' is the number of half wavelengths in the antenna. The result is 102.57' or 31.27 m. It is interesting that Varney notes in his 1984 article in RADCOM that he can shorten the wire to 102' or 31.1 m, since the entire system will be handled by an antenna tuning unit (or ASTU--antenna system tuning unit--as Varney preferred). (The entire 1984 article has been reprinted in Erwin David, G4LQI, HF Antenna Collection, published by RSGB in 1991. In the G5RV article, the author makes reference to his initial 1966 presentation of the basic idea. An adapted version appears in The ARRL Antenna Compendium, Vol. 1, 1985.) However, we conventionally sketch the G5RV antenna system as in Fig. 1. The center-fed doublet has a section of parallel transmission line extending from the radiating wire feedpoint to a junction with the "main" feedline. Curiously, Varney specifies the length of the matching section as 34.0' or 10.36 m.

  • Antenna System Re-Visited Part 1: the G5RV on 20 Meters
    The G5RV Antenna System Re-Visited Part 1: The G5RV on 20 meters L. B. Cebik, W4RNL Louis Varney G5RV was and is not an antenna, that is, an array of elements. The antenna he designed named after his call sign, the ‘G5RV’ is an antenna system including a radiating element and a length of RF Transmission Line designed to present a "correct" impedance at a design frequency. The 1984 RADCOM Version of the Antenna System The most familiar part of the system is the wire: a center-fed doublet 102' long. Actually, Varney calculated the length to be 3/2 wavelengths long at 14.15 MHz using a long- standing equation: The letter 'n' is the number of half wavelengths in the antenna. The result is 102.57' or 31.27 m. It is interesting that Varney notes in his 1984 article in RADCOM that he can shorten the wire to 102' or 31.1 m, since the entire system will be handled by an antenna tuning unit (or ASTU--antenna system tuning unit--as Varney preferred). (The entire 1984 article has been reprinted in Erwin David, G4LQI, HF Antenna Collection, published by RSGB in 1991. In the G5RV article, the author makes reference to his initial 1966 presentation of the basic idea. An adapted version appears in The ARRL Antenna Compendium, Vol. 1, 1985.) However, we conventionally sketch the G5RV antenna system as in Fig. 1. The center-fed doublet has a section of parallel transmission line extending from the radiating wire feedpoint to a junction with the "main" feedline.
