Model 1110d - 1:1 Isolation/Choke balun 1.5-54 MHz - 300 Watts
$69.95This low power balun is one of our newest offerings and provides over 30db of suppression across the full HF spectrum of frequencies. Our design provides high levels of feedline isolation, RF choking and excellent return loss for those who want high...$69.95 -
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 4114 - 4:1 Current Balun 1.5 - 54MHz 5kW
$94.95This balun is an excellent step up from the model 4113 and is not sensitive to high power reflected RF like the model 4115. The design is the perfect choice for two types of operation. First, if you transmit high power (=>1kW) in to a...$94.95 -
Model 4115 - Dual Core 4:1 Current Balun 5kW 1 - 54 MHz
$113.95This is a balun originally designed by Guanella and subsequently improved by Dr. Jerry Sevick (W2FMI). By utilizing Thermaleze wire inserted in Teflon tubes, Dr. Sevick was able to substantially increase the breakdown voltage between both conductors and...$113.95 -
Model 4116 - 4:1 Hybrid Balun 1.5 - 54MHz 3kW
$114.95This is a great all purpose 4:1 current balun designed for those who would like the combination of a 4:1 balun capable of tolerating a compromised antenna installation and still provide a high level of performance. This unit is a great choice for...$114.95
