DX Engineering Maxi-Core® High-Power Multi-Band UNUNs
DX Engineering High-Power Multi-Band UNUNs with Maxi-Core® technology allow your antenna to perform to its fullest potential and reduce stress on your equipment.
These specially tuned UNUNs, designed for non-resonant vertical antenna applications, operate more efficiently than similar competitive products. Lesser products may burn up easily on lower bands with QRO power levels.
DX Engineering high-power UNUNs are specifically designed for applications with 43 ft. non-resonant, multi-band antennas, ensuring the best efficiency from your antenna and transmission line/tuner installation. The results are minimizing the additional transmission line losses caused by abnormally-high SWR.
DX Engineering Maxi-Core® High-Power Multi-Band UNUNs can be added to any existing 43 ft. antenna installation or used to replace an older competitive UNUN for a performance increase. The UN-43-R includes mounting bracket and feed-point connections braids.
Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.
All non-resonant vertical antennas present high SWR to their feed lines. Deal with it! Order DX Engineering High-Power Multi-Band UNUNs!
