Gentlemen... Here we go again... so which is it? Inverted L's have plenty of bandwidth or Inverted L's little bandwidth??? First, let me say if you are not taking your measurements AT THE FEEDPOINT,
Tom, I do not have engineering specs for the Tri-EX T-588, but I do have 6 pages out of the 1971 catalog that you can download here: http://tinyurl.com/og7j3 Five files are 1.5-Mb each, and Tri-EX-04

Hi Pete, Can you elaborate on the "1750 Hz (measured at 28 MHz) of 3/4" CATV" you mentioned? First, I assume you meant 1750 KHz, but aside from that, I'm not following what you mean. Also, measuring

FB! Pete, Regarding your measurement at 28 MHz idea... Last winter I wanted a 1/2 wavelength feedline for 1830 KHz. I used my AEA HF VIA Analyst to tune the coax. The AEA has a computer interface and

Allen, We just had a discussion regarding masts on the Minnesota Wireless Assn reflector. You can use this on-line mast calculator to determine whether an aluminum or steel mast is needed for your sp

Digging around in the archives I learned it was Telrex that manufactured the "Big Bertha" system in the 1950's ~ 70's. Rich, KE3Q, had a good write-up about this company and their product line. This

Hello Al, With this new engineering obstacle in your path, you need to start looking at heavy duty towers, as suggested in other parts of this thread. Having to provide a design with 1/2" of radial i

Yo! Bob, This just does NOT compute! That's 1200 feet of Cat5, or nearly 10,000 feet of wire. You said this was a wireless project? This must be along the lines of the paperless society by 1985, righ
