Best Kept Secret in Ham Radio  Time owned: unknown months
I use the 87 Ft Model. As the other review states the resonactors will not burn out with legal limit power. The coils are wound so that they dry out in normal weather and do not collect moisture or spider webs. The tuning stub method of resonating each band allows tuning of each, if you start with the 10 meter (shortest) band and work down to 80 Meters. I have never had a wire antenna that has shown flat SWR on all of the bands from 10 thru 80. While the WAF (wife acceptance factor) is not as high as would be with just a simple wire antenna, the inline coils (resonactors are about 2" in diameter and 2 1/2" long) and there are one foot wooden dowels seperating the two dipoles, it is worth listening to the noise from the XYL for the good resonance that the system provides. One of the net control stations told me to wait a minute before I responded so he could turn down his volume. And I was only running about half legal limit.

This antenna is worth the price if all you get from it is the education in antenna design and tuning.

A cost effective high-performance 5 band antenna  Time owned: unknown months
W9INN has tiny ads in QST and CQ. He deserves full-page ads since his MPD-5 is a real scorcher of an antenna. It is a fan dipole with 2 wires of each side of the center connector seperated by wooden dowels. There are 2 models...78ft and 87 ft long with differing bandwidths. My 78ft model gives great SWR on all bands including 80M where it has about a 120KHZ 2:1 bandwidth. It takes full legal power and has no traps. Instead Bill uses what he calls 'resonactors' which act as a trap but have no physical capacitor component to ever fail. He pre tunes the antenna for you according to your specs. Mine was up and running in an hour. It features easy-to-use stub tuning for all 5 bands. I have 236 DXCC countries on Bill's antenna most with only 100W. Sells for around $100. Look for his'll need your magnifying glass!
