I suspect that what your field strength meter is sensitive to are volts/meter, or the electric field strength not the magnetic field caused by the area of max current flow in the dipole. So, yes, wh
Believe that would be a fine choice. I have one of their MA-550's with motor out here for last 11 years. Had to get a new one once as I allowed the cable to rust through, and it broke! Too much dama
To obtain 75 ohm twinlead, go to: VGE has been selling this twin line for years and years. And it is TOUGH to work with! Very difficult to get into to strip/splice. The two conductors are VERY close
Aloha from Kauai, Here is a link showing my tubular tower with the Force 12 C3 at both 33 feet, and with the tower cranked full up at about 60 feet. It is directly beside the house. A lot of photos

Hi, Yes, today is equinox day here on the Island of Kauai. Sunrise this morning here was at 6:47 AM, HST; sunset this evening will occur at 6:47 PM, HST. Thus, 12 hours of daylight and 12 hours of ti
Out here, about 30 to 45 minutes before sunrise, and continuing throughout the day, a brilliant red Cardinal sits right atop the mast on my "tower" (well, only about 35 feet high now, cranked down).
T'was wondered..... I have a F12 EF-140S up on my C3 boom. It has been NG for several months now! Why? I have no idea.... tried it again this afternoon during the Hawaii Afternoon Net. It lasted a fe
Hi Chris, When the capacitor assembly is fully meshed, the C value is highest. Now that may NOT be when the adjusting knob on the face of your tuner is set to the max number value shown! For some re
I have had two UST MA-550's over the past nearly 11 years. The wire rope (cable) on the first rusted through after about 7 years in our tropical weather here on Kauai. When the tower "collapsed" the
Seems to me that with that set up, the main "beam" of the transmit antenna would be high in the sky, way above the "beam" of the rcv antenna under test. Or do they assume both beams will intersect u

The operating theory for this tuner is, well....amazing: "The electro-magnetic field generated by a dipole matched with a MAXX-COM device is somewhat different than with a resonant tuner. A resonant
