After investigating a large set of traveling wave antennas (not Beverage) I think that the smallest amount of power dissipated in the terminating resistance was about 2 db. Mind, these were antennas with useful lengths and angles. It is likely that a rhombic with very long leg lengths would dissipate even less in its termination resistance. Well, remember the posting that kicked off this discussion was about the following very short traveling-wave antenna: "It is a military inverted-V, 110 ft. long total, with each end terminated in a 150 ohm resistor driven into the ground, center fed through a 9:1 balun." A 110 ft. center-fed inverted-V is certainly going to have extensive losses in the resistors on most HF bands. After all, it is less than 1/2WL long on 75m and only 3 wavelengths long on 10m. -- 73, Cecil, W5DXP -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
