CURRENT BALUN

 

  • Each balun and antenna is hand crafted, built right here in the USA.
  • Using the best materials.  
  • The ferrite cores are 2 1/4" in dim. using 240/61 material. Teflon wire.
  • It is encased in 3 inch pvc round tubing. 
  • Stainless steel hardware is used.
  • Double aluminum ferrals are used to hold the wire in place on the balun double machine crimped.
  • The wire used is Flex-Weave 14, Poly Stealth 13, Hard drawn 14, #12 stranded. 
 
Can be used as a off center fed shortwave antenna to provide continuous coverage from 500 kHz to 60 MHzSWL


Quickly switch bands and eliminate a tuner as one more thing to adjust. Eliminate send/receive tuner loss.

Due to the fact that one wire leg of the antenna is shorter than the other, the OCF is more convenient to erect than a regular center fed dipole. Less coax is required.

Check the SWR always BEFORE using with any antenna tuner.

The dipole is constructed using top quality, FLEX-WEAVE TM is a sophisticated hybrid aerial wire. Its new innovation provides rope lay construction strength and high flexibility. It can be tied in knots to insulators and untied for repeated use. FLEX-WEAVE TM is sometimes referred to as "wire rope" or "jewelers rope". It will not kink or rust out as will copper-clad wire. This flexible wire has also been used for rapid deployment, spool-out, military aerials.

 FLEX-WEAVE TM  #14 (168 strands of #36 wire).  It is excellent for quads, dipoles, long wires, and rapid deployment (spooled-out) antennas. Highly UV resistant PVC jacket.

 FLEX-WEAVE TM is the "Cadillac of aerial wire". It has been written about in all amateur radio publications since its introduction in 1989. This revolutionary product has been used by thousands of hams, commercial firms, and government agencies.

The insulation has superior abrasion resistance for running through trees and is UV and weather resistant for use on the seacoast or in other harsh environments. They'll stand up to acid rain, high wind loads, and high snow and ice loads. 

 NOTE: Some bands will require the use of a tuner. Do not try to load 80 meters with a outboard tuner on the 160 OCF if the SWR is high it will result in damage to the cores and your equipment.

No trimming - fully assembled, complete and ready to go with end insulators and crimped center and end connections.

Add your 50 Ohm coaxial feed line, suspension rope and go

 

Can be hung Flat or inverted V configuration.     Remember stay away from power lines.

  1. 2nd OCF antenna purchased hete! 5 Star Review

    Posted by on 16th Nov 2015

    This is my second 7 band OCF antenna purchased here. The first one I put up 3 weeks ago st 35 foot center inverted V. Upon checking the antenna with my antenna analyzer I found the SWR across all bands to be very low. OK now for the real test. Went to the shack and verified the SWR readings on my Powrr Master 2 meter . OK still very low on all bands. I fired up the Flex 5000 and AL82 and started making contacts on all 7 bands. Great reports. Antenna hears really good and works well when transmitting!!
    I ordered a second OCF antenna for my permanent campsite.
    I will be installing it in the spring when the campground opens.
    Great antenna that I highly recommend !!!


  2. Well done 4 Star Review

    Posted by on 10th Nov 2015

    I gave it a 4 star instead of a 5 star only because I have not actually used it yet.
    I bought it as a secondary antenna so was not too concerned about it, but I found the quality of materials and construction to be top notch. A windom is a windom so I know what to expect in performance but this is much better made than I was expecting for the money.
