  • Antenna Factor  The decibel, a difficult unit All antenna manufacturers specifies the gain of their VHF/UHF antennas in decibels, or dB for short. The problem is that decibel is really only a ratio, not a fixed .

  • Antenna Application Note 47899   note on this site, many rumors and misconceptions exist in the amateur radio world about stacking VHF/UHF antennas on the same mast. One of these is that you have to space yagis far apart to make.

  • http://w3eax.umd.edu/~ham/resume.txt   transmitters, HF through UHF, and accessories. Designed, constructed, and installed HF/VHF/UHF antennas. Familiar with error-correcting codes, AX.25 packet, and other digital modulation techniques

  • N2000XU Fund Raising Goals Goals  expansion. In short, the club wants to add a new tower so that additional HF and VHF/UHF antennas can be installed. This expansion will give members the greatest variety of operating activities.

  • RT] Antenna Field Measurements   The only _accurate_ way to determine the radiation patterns >> of VHF/UHF antennas is on a calibrated test range.
