Another option would be one of the premix places which supply a small trailer which holds ~1 yard. You can tow it (carefully) with a small truck and two people can manhandle it around to the pouring
Non-scientific observation: I'm located about 500 ft. from a narrow inlet north of me about 500 feet across. I've noticed that my horizontal wire antenna located ~20 feet above ground (sloping a bit
It has been about 35 years since I have done any work in this area, but I recall that the type of "tilted" antenna described was generally referred to simply as a log-periodic array, not a log-period
A hazer is a platform for the rotator, mast and antenna which rides up and down the side of the tower, pulled by cables (see http://www.glenmartin.com). I remember Charlie Biddle (W6CN?) had a simila
Fairly simplified version: Each element radiates in both directions, but the resulting pattern is the vector sum of the radiation of all of the elements. This is dependent on the location of the elem
The only reason the FCC granted preemption for satellite dishes (plus MDS and "ordinary" TV antennas) is that Congress explicitly directed them to do so. Their reluctance to extend this to amateur an
LMR-400 isn't shown on that link, but the Times Microwave ads show a loss of 2.7 dB/100 ft at 440 MHz. -- Bob Nielsen, N7XY nielsen@oz.net Bainbridge Island, WA http://www.oz.net/~nielsen IOTA NA-065

Stated somewhat differently, use as much tower as the length of the feedline will allow. -- Bob Nielsen, N7XY nielsen@oz.net Bainbridge Island, WA http://www.oz.net/~nielsen IOTA NA-065, USI WA-028S
Just don't take too seriously the blurb on the MFJ web site where it says "3 feet of ruthless radiating power". Does MFJ supply the additional parts needed to lengthen the 20 meter stub for use on 30
In my freshman chemistry class at Caltech, the prof (Linus Pauling, no less) used to work out a problem on his 6 in. slide rule and recite the answer to 6 or 7 digits. We all knew he had a sheet with
