Ununs are used for matching an unbalanced antenna to an unbalanced feedline. Feedline chokes keep noise out of the antenna and the receiver to improve overall reception plus they reduce RFI by eliminating feedline radiation. Enjoy maximum power transfer, optimum balance and a lot less noise. Shop... Read More
Model 9135 - 9:1 Unun 1.5 - 54MHz - 5kW. Current Production Time 7-9 Business Days. This design is excellent for matching both long and short length unbalanced long wire antennas for multiband use and will allow the internal tuner of most rigs to match a single long wire antenna.
My EFHW is probably good to about 50W (I built my unun on a BN-43-3312 binocular toroid, which is pretty beefy), but a lot of the ones people use are definitely QRP-only. The MFJ verticals are good to full QRO power.
An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground.
64:1 / 49:1 Unun. 3.5-30 MHz. 1 kW power handling. Insertion loss 0.3 to 1.65 db based on frequency. Studs on side. Silver plated SO239 connector. Price excl VAT: £ 128.41.
