The # 1 selling BALUN

At BUX COMM, *We don't cut corners!

The elements used in the development of our BUX BALUNs are manufactured from top quality components, beginning with the Silver Plate SO239 connectors and center insulator, made of teflon™(E.I Dupont).

The wire we use to wind the ferrite donuts is heavy-duty, silver flashed wire, with teflon™ insulation that will handle RF voltages above 15000 volts, and temperatures to 1000 degrees. The binding posts are heavy-duty, tempered brass, with end holes and side-thru holes to accommodate either type loop-thru connection. A double-shoulder brass capture nut is used to add a secure bite and improve antenna wire electrical connections.

BUX BALUNS are analyzed and tested in our lab, using a General Radio Impedance Bridge (GR1145) and Rohde & Schwarz, Vector Signal Generator and RF Spectrum Analyzer, (SAM300) from 9 kHz -3 GHz to a WALFEUR 3000 watt, step range Pyronol-Dummy Load (SRDL3K).

With our BUX UN UN (ONION), the coax is Belden™ RG8X and the PL259 connectors are Amphenol™ with Silver flashed SO239, and Gold center pins. Center Insulator is Teflon™ (EI DuPont)

MasterMatch� 4:1
BLACK HAWK

$19.95 MM41

Our BUX Master-Match� 4:1 current Balun is ideal for matching windoms, web'd or folded dipoles, and antennas fed at a 250 ohm to 500 ohm impedance feed point with normal 50 or 75 ohm coax cable. In contrast to ordinary Baluns the BUX MasterMatch� 4:1 Balun support balanced currents in each leg of the antenna and prevents feedline (re)-radiation. As mentioned in our windom articles, feedlines and 450-ohm, brown, UV resistant, PolyCovered-Ladder-Line are easy to handle, and more-over they present another efficient means to feed multi-band antennas. We strongly suggest the use of our UV resistant PolyCoat-Ladder-Line as it is made of strong, copper-clad, steel conductors. This light but durable, UV resistant Ladder-Line will outlast the normal open copper with plastic spacers. (Includes three FREE antenna insulators, shown elsewhere, this page).

Master-Match� "Black Hawk" 4:1 Features:
o DynaMAX Colored and Hardened, UV Resistant Resin, Enclosure
o Toroid CURRENT design, wound with teflon covered, silver flashed, copper wire.
o 50 ohm, silver plated, gold pin, teflon center insulator, SO-239 unbalanced input
o Heavy duty Hardened Brass, Balanced output terminals.

At BUX COMM, *We don't cut corners! The components used in the manufacture of our BALUNs are from top quality components, beginning with the UV resistant enclosures, then the Silver Plated SO239 connectors with center insulator made of teflon�(E.I Dupont). The wire we wind the ferrite donut with, is heavy-duty, silver flashed wire, with teflon� insulation, which will handle RF voltages above 2500 volts, and temperatures above 400 degrees. The binding posts are heavy-duty, tempered brass, with end holes and side-thru holes to accommodate either type loop-thru connection. A double-shoulder brass capture nut is used to add a secure bite and improve electrical connections to the wire .

$19.95 Order MM11

BUX Master-Match� 1:1 current Balun is ideal for Dipoles, Slopers, Inverted-Vees and center feed-point, RV antennas. They are also employed at the driven element of of many HF beams and Quads, and where feedpoint impedance is at, or near 50 ohms. By equalizing the currents in the antenna feeders, the Dipole pattern improves and prevents feedline (re)-radiation by preventing antenna currents flowing along the outer braid of the coax or transmission Line.

Dipole and inverted-Vee antennas are commonly "balanced" at the feed points. Coaxial feed lines are "unbalanced" by design personality (thus the name BALUN). This BALANCED, to UNBALANCE marriage can only be performed by using a BALUN. A BALUN should always be used when feeding wire antennas with coax to make certain characteristic antenna performance and optimum transfer of RF energy to the antenna complete.

When coax is used to feed antennas without the benefit of a BALUN, current flows on the shield of the coaxial feed line . This coaxial shield current can produce a "Hot HAM shack," This can result in nasty R.F. injury from the microphone to lips, hand key to fingers, etc., and is often more pronounced at certain frequencies. Coax cable shield currents can also cause damage to your HAM gear. TVI, RFI, telephone and even wild VSWR indications can result from these shield currents.

In 85% of antenna projects that displayed these problems, when a BALUN is added to the coaxial line or near the antenna feed point, these problems were diminished or completely eliminated.

Important Information; WHY USE A 4:1 BALUN

Krusty Olde Kurt is now going to repeat himself. Why? Because the same question keeps coming up over and over. And he wants everyone to get it right. "I'm feeding my dipole with 600-ohm line. At the station end I need a balun to convert to 50-ohm coax. I need a 12:1 balun, right?" Wrong! A 4:1 balun would be better. Why is that? If your dipole is up, let's say, 35 feet then on 80 meters it will probably have a resistance at resonance of about 40 ohms. The actual resistance depends on the height above ground in wavelengths.

If the dipole is 40 Ohms then what do you see at the transmitter end of your 600 ohm line? If the line is a half-wave long (120 ft on 80 Meters) you'll see 40 ohms. Remember, a half-wave line repeats what it sees at the other end. But if it is a quarter-wave long you'll see 8500 Ohms! At other line lengths you'll see impedances somewhere between these two extremes. So you are not going to see 600 ohms at the end of your 600-ohm line. That only happens if you have a 600-ohm antenna hooked onto it. With such a variation in impedance at the trans�mitter end of the line there is no one balun transformer that will match it. Most of the time the impedance will be above the 50 Ohms of your coax so a high impedance balun would be desirable. Unfortunately high imped�ance baluns don't work well when not matched.

Experience has shown that 4:1 baluns work best in this service. They are more rugged and will take bad mismatches especially if they are wound on an iron powder core. So stop searching for that 12:1 balun. Use a 4:l BALUN and your system will work great.

You can read Kurt N. Sterba �AERIALS� column in World Radio Magazine.

With an increase in local noise sources and the increasing attractiveness of long wire and dipole antennas, coax cable has become the antenna feed line of choice for most radio users and operators.

Given that the impedance of most commonly available coax is either 50 or 72 ohms and since many wire antennas present an impedance of 200 to 600 ohms or more at the feed point, direct connection of the coax to wire antennas hits us with a significant signal loss due to the antenna impedance mismatch.

Having realized this set of circumstances in the receiver and SWL arena, we're introducing a new approach to defeat the noise and impedance mismatch problems in our receive antennas by designing this new RxBALUN�.

Our RxBALUN� bridges the impedance gap, and enables an unbalance to balanced match between the antenna and our receivers. These features provide more signal transfer from the antenna to your receiver.

Our RxBALUN will accommodate the SWL and QRP Operator. In addition, this RxBALUN may be employed as an antenna balun for both transmit and receive between the antenna and low powered transceivers running up to 200 watts. For input and output connectors, we use only the best Silver plated, Teflon�� insulated, SO239 connectors. Max Power 250 watts.

TUNING INSTRUCTIONS:
Insert the whip into lower section ferrule about four inches (as shown at right) and tighten set screw. Assemble with fiberglass lower section (as shown at left). Install a VSWR meter at the transceiver and apply 10 to 25 watts of power. Adjust the VSWR meter and output frequency for lowest VSWR reading, indicating resonance. If resonant frequency is too high, loosen set screw and extend top whip until desired resonant frequency is found. If resonant frequency is too low, loosen set screw and adjust whip further into lower section. For best results, adjustments should be made in small increments.

CAUTION: If required, cut off the bottom of the whip to ensure it does not extend down into the coil of the antenna. Failure to observe this precaution will cause heat damage and void any warranty. At resonance, VSWR should be 1.5:1 or less when properly matched. When tuning is complete, tighten set screws securely. NOTE: Bandwidth and VSWR will vary due to mounting location. If your installation has a VSWR over 1.5:1 at resonance, or you need to operate over a greater bandwidth a tuner may be required.
