Model 1115u-u - MA5B Balun 1.5 - 54 MHz 3kW
$103.95We have updated and modified the design of this unit to allow the use of a common UHF "tee" on the output for the dual feed of the MA5B yagi. This allow us to build for a lower cost and reduced time which we can pass along to the buyer. ...$103.95 -
Model 1142s - 1:1 FCP Isolation Transformer 2kW
This is a unique 1:1 transmission line transformer intended to provide highest possible isolation between input and output. Consequently there is no direct electrical connection between the input and output with all RF energy being...Qty in Cart: 0Price:Subtotal: -
Model 1151 - 1:1 ATU Current Balun, 1 - 54 MHz, 2kW
$79.95This new release provides excellent choking and feedline isolation across the full HF spectrum, but is a departure from the normal 1:1 isolation/choke balun. Rather than a 50 ohm characteristic impedance, this balun utilizes a bifilar pair designed...$79.95 -
Model 1161 - 1:1 ATU Current Balun, 3 - 54 MHz, 5kW
$94.95This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize inter winding breakdown voltage. This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize...$94.95 -
Model 1171 - 1:1 ATU Current Balun, 1 - 54 MHz, 5kW
$94.95This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize inter winding breakdown voltage.found on multiband antennas such as doublets and multiband loops. The balun functions to transform balanced...$94.95 -
Model 36130 - 36:1 for EFHW, 150 watts
$71.95This is the latest and greatest transformer design for End Fed Half Wave (EFHW) antennas. Researched and developed by Bob Glorioso, W1lS and Bob Rose KC1DSQ, they discovered that most transformers for EFHW antennas used higher impedance...$71.95 -
Model 36131 - 36:1 for EFHW, 800 watts
$104.95This is the latest and greatest transformer design for End Fed Half Wave (EFHW) antennas. Researched and developed by Bob Glorioso, W1lS and Bob Rose KC1DSQ, they discovered that most transformers for EFHW antennas used higher impedance...$104.95 -
Model 4124 - 4:1 Tuner Balun 1 - 45 MHz 5kW
Jerry Sevick (W2FMI) specifically researched and designed this tuner balun to provide a very constant 50 ohm input impedance on the lower frequencies where most baluns can drop by 20-40%. In addition, the Thermaleze wire/Teflon tube windings on a...Qty in Cart: 0Price:Subtotal: -
Model 4145d - 4:1 Upgrade Balun for Drake B-1000
$83.95For those of you who own one of the fine tuners manufactured by Drake, this is a balun that can be easily installed on your existing PC board in place of the original windings. If you do not currently own a B-1000 balun, you can elect to mount this balun...$83.95
