Therre is only one these days thats worth a hoot. Its the 'all frequency'
SteppIR. Do a google on it, and read all the comments. You can tune it to 'any' frequency from 6.9 to 30Mhz and they are coming out with a 80 meter kit... Its a optimized single band vertical on 'every' frequency, no traps, coils, any of that bs... Jerry.. "Glenn AA5PK" wrote in message news:TlmKc.21102$SD3.8371@okepread06...

Total coverage, it will tune anything your radio can tune! Thats the beaut
of it, it acts/tunes one hz at a time continuous. I was wrong about the coverage however, it doesn't stop at 30Mhz, but goes all the way up to 52Mhz! No traps, coils, capacitors or linear loading of any kind. Full continuous coverage, including WARC bands-without compromise! Fiberglass element resists wind and ice. Low visual profile - excellent for stealth installations. Works on the same principle as our Yagi - copper stip adjusts inside of fiberglass element. Antenna is always at ideal length- No running outside to make adjustments. The safest vertical antenna in the world! "The radiating conductor is completely insulated at all times by the telescoping fiberglass tube and antenna housing, protecting children and pets from potential hazards." Finally!, A high performace, low VSWR vertical antenna with excellent bandwidth and no compromises ! Verticals are available that cover 40 meters through 6 meters by using coils, traps, capacitors or linear loading, but do so at the expense of significant performance reduction. With the addition on the WARC bands on 30m, 17m and 12m, multi-band vertical antenna performance has clearly become a challenge. A vertical antenna that is precisely adjustable in length while in the air solves the coverage problem, and in addition has vastly improved performance over existing fixed length verticals. The ability to tune the antenna to a specific frequency results in excellent performance on every band - and this means the entire band, with very low VSWR. Resonant antennas must be made a specific length to operate optimally on a given frequency. So, instead of trying to "trick" the antenna into thinking it is a different length, why not just change the antenna length? This is what we have done with the new SteppIR verticals. Each vertical antenna consists of one spool of flat copper strip conductor mounted in the antenna housing. The copper strip is perforated to allow a stepper motor to drive it with a sprocket. Stepper motors are well known for their ability to index very accurately, thus giving very precise control of the antenna lenght. In addition, the motors are brushless and provide extremely long service life. The copper strip is drive out into a hollow, lightweight fiberglass support element. This telescoping support element stays extended at all times, while the conductive strip is adjusted to the exact required length using the microprocessor based controller (via 22 gauge, 4 conductor shielded control cable). The antenna is easy to assemble and is extremely portable. "Maxcom" wrote in message ... For what bands? "Daphne + Dave" wrote in message news:9cmKc.51922$ek5.39359@pd7tw2no... Any comments?
