80-6M 100W HF Ham Radio Antenna OCF Off-Center Fed Dipole - Free Shipping
A Stealthy, Lightweight, 100 Watt 80 thru 6 Meters
Multi-band
Dipole for Home, Portable and Base Station Operations.

This antenna is the result of amateur radio lessons learned, one of which is -
if you
can
put up a dipole, you
should
.
Multi-band antennas can be a great convenience at times. For those occasions, we now offer a multi-band dipole that covers 80 Meters in a compact, durable form with exceptional performance at a reasonable price. Check out our antennas in action on YouTube, simply search "N9SAB Antenna" for some excellent Ham Radio content by such providers as Ham radio Concepts and Outdoors on the Air.
For 9.95 you will receive:
One original, newly fabricated, 100 Watt off-center fed dipole with integrated 4:1 matching transformer as depicted in the photos, tested and described below. Made in America with materials sourced from U.S. sellers
A UHF SO239 end protector cap
A camouflage drawstring string carry pouch as pictured

People familiar with our antennas already know that compact, light, effective performance means a dipole, to us. The difference here is that we now offer all the highly portable characteristics of our regular antennas in a
multi-band
off-center fed dipole now for
80 through 6 meters
. This is the very same antenna I use for my home QTH.
This antenna requires a tuner.
Fortunately, there are many compact, portable tuners available and many newer radios include an auto-tuner. If you are equipped this way, then our OCF Dipole is for you. Our antennas are solidly built, rugged and designed to be a high-performance
value alternative
to much more expensive equipment. Don't take our word for it, please check our feedback as a seller.
The antenna is an 80 Meter half-wave dipole fed 1/3 of distance from the end. This raises the feed-point impedance to approximately 200 ohms. To compensate, the antenna is equipped with a 4:1 Ruthroff -style voltage balun (impedance matching transformer) embedded between the UHF female connector and the 18 AWG UL1007 elements (See schematic with photos). The transformer uses one (1) FT140-43 ferrite toroid. The result is a highly functional OCF dipole for use on 80 through 6 meters.
Using a Yaesu FT-450D as a transmitter and auto tuner, our OCF Dipole tunes between 1.1 to 1.5 SWR on all bands 3.5.000 to 54.000 MHz. There is a band by band SWR readout in the photo section showing values without a tuner. If your tuner can compensate less than 8:1 SWR (most do better) then you will be able to effectively transmit on 80, 40, 30, 20, 17, 15, 12, 10 and 6 meters. Perfect for outdoor or stealth operation. Perfect for a base station antenna. It's also a great, inexpensive gift to give to those involved with amateur radio that requires
no additional finishing.
It fits easily into a pocket, glove box, bag or carrying case.
Many experienced hams would agree that it is very easy to erect an antenna system inferior to a dipole, and very difficult to out-perform one. There are no short-cuts or electronic tricks involved here. The balun design and schematics are straight out of the Antenna Handbook. All electrical connections are soldered using silver bearing rosin-core solder. Parts and connections have been weather proofed using marine-grade, adhesive-lined double walled polyolefin shrink tubing.
The 80 Meter OCFD weighs under 20oz. (566 grams) and fits into a space 9" x 3" x 3" (229 x 77 x 77mm) when folded. Extended, the dipole is cut for the 80 meter band with one element approximately 47 feet in length, the other approximately 83 feet. It can be used in any of the standard dipole configurations, flat-top, inverted V, sloper, vertical dipole, wire vertical w/counterpoise, etc. but the patterns achieved through different configurations
are not the same
as with a classic half-wave dipole in a standard configuration.
