Model 1115d - Isolation/ Choking 1:1 Balun, 1.5-54 MHz, 5kW
$94.95Building on the original 1:1 design by Dr. Jerry Sevick, this balun has two (2) low permeability cores in a stacked configuration to maximize choking impedance on HF bands from 7- 54MHz. By utilizing Mil-Spec coax, the SWR, transformation and power...$94.95 -
Model 1116d - 1:1 Balun, Optimized for Low Bands, 5kW
$94.95This Isolation balun is identical in design to the Model 1115d but with one key exception. The toroid material utilized for the two stacked cores is optimized for the lower HF bands and provides exceptional choking impedance at these frequencies. In...$94.95 -
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 handle the high voltages typically found on multiband antennas such as doublets and multiband loops. The balun functions to transform balanced twin...$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
