UNUN 9:1 5kW

RCT-91150

RCOMTECH High-Power Baluns and Transmission Line Transformers let your antenna perform to its fullest potential and reduce the stresses on your equipment. RCOMTECH baluns will deliver the power to your antenna with minimum loss and perform a perfect transition from balanced to unbalanced. This will result in the strongest signal that your antenna is capable of producing consistently with the lowest SWR under given conditions.

This results in less stress on your transmitter so that components will last longer and operate better. RCOMTCH baluns exhibit far wider bandwidths than conventional baluns because more of the flux is confined to the immediate vicinity of the core, so much more energy goes to your antenna. Extremely high efficiency is achieved over the entire frequency range.

9:1 UNUN characteristics

Custom imported high efficiency low permeability ferrite with coating seal
Widest operating frequency range
Lowest core pressure
Eliminate common common mode currents and radiation from feeders
Reduce transmission RFI and receive noise
Insertion loss is less than 0.02 dB
High standard waterproof box, long-term anti-UV
SO-239 nickel plated connector with waterproof gasket and TEFLON insulation (optional silver plated -X)
lifetime warranty

Please select the longest cable length in the list that suits your environment. The SWR changes depend on your geographical environment, ground conditions, ground network and other factors. The data in the table is for reference only (higher SWR available days) Tune as an aid). More blocking common mode current and radiation, reducing transmission RFI and receiving noise, you can choose dual SO-239 isolation balun 11001, 11003, 11010, 11030, 11050, install the nearest location with UNUN. If the long-line antenna is inverted L-shaped, it will change the impedance of the feed and the tuning (the length of the fine-tuned line as needed) to cover all HF bands.

Select one or more ground wires of different lengths (20-50 feet) to connect to the balun grounding terminal, and the ground net is away from the long-wave oscillator.

91101、91103、91110、91120、91150 are recommended as first for wire length.
