Reviews Summary for Balun Designs 4:1 Current Balun 1.5 - 40 Mhz for Dipole / Yagi 3
Balun Designs 4:1 Current Balun 1.5 - 40 Mhz for Dipole / Yagi 3 Reviews: 3 Average rating: 5.0/5 MSRP: $66.95
Description: This is a Current balun that will handle very high power over 1mhz
to 40mhz. It's a perfect choice to feed multiband and off center
fed dipoles, Windoms and Zepps.
* Special mix toroid provides broadband coverage. Toroid is coated
with epoxy paint for extra durablity.
* The design has excellent low frequency response which makes them
very efficient (98-99%). This balun performs well on 160, 80 and
40 meters where most dipoles are used but because of the short
length windings, works just as well up through 10 meters. Input
impedance remains essentially flat across this frequency spectrum.
Competing designs can very as much as 40%, especially at lower
* 2 separate bifilar windings of 14 gauge Thermaleze wire. This is
NOT the enameled type (Formvar) used by my less expensive
competitors. It is coated with a polyimide covering rated at a
minimum of 2000v breakdown voltage. The windings are then inserted
into teflon tubes which increases the total breakdown to 10,000 volts.
* Typical insertion loss is < 0.2db
* SO-239 connectors are silver plated with teflon insulation.
* All hardware is Stainless Steel. Eyebolts and studs are 1/4"
* N connector and Alternate mounting options are available in
* Because of the high efficiency, this balun will not heat up or
saturate like the typical cheap current baluns using ferrite rods,
beads or open air wound coax.
* The balun is installed in a weatherproof 4" X 4" X 2" NEMA Box which
is an ideal enclosure for those who want to mount the balun remotely.
The enclosure has four legs on the back side which can be used to mount
to our Balun Mounting plate for mast mounting. The balun can also be
built with studs on the top or sides of the enclosure for connection to
ladder line, to use with yagis or for other applications that require
this connector design.
Product is in production.

Another satisfied customer  Time owned: 6 to 12 months
Replaced the Buckmaster 6:1 voltage balun that failed due to lightning.

Works perfectly on my OCFD with center at 55 feet. Rugged. Quality build.

Used it previously on a collinear 17 meter antenna to match coax to ladder line.

5 out of 5  Time owned: 6 to 12 months
Currently using this 4:1 balun to feed a horizontal 80 mtr loop, 450 ladder line, from 160 to 10 mtrs through a very heavy duty home made antenna tuner. The amplifier here is a Command Technologies HF 2500. This balun doesn't have a problem with the high voltage related to the high power, VSR, and the different frequncies. Excellent quality. You can't do better. If you have had other baluns that won't quite cut the mustard give this one a try.. it will work!!

Makes my OCF Dipole Sing!  Time owned: 0 to 3 months
I have used this balun in constructing an OCF Dipole designed by a couple of local hams. It has performed well on 80M. 40M and 20M. The quality and construction of these baluns is top notch!
