Product Description for 1kW 49:1 High Power Matching Transformer

49:1 High Power Matching Transformer for Multi-Band End Fed Half Wave Antennas

Perfect for home or field use, this high-power matching transformer can handle up to 1kW PEP.

Easy to Set Up Simply add your preferred antenna wire. The UK manufactured Kevlar wire is recommended (see accessories).

Flexible Antenna Lengths

  • Attach 132ft of wire for 80m, 40m, 20m, 15m, and 10m bands.
  • Use 67ft of wire for 40m, 20m, 15m, and 10m bands.
  • With an AMU/ATU, you might also get 30m, 17m, 12m & 6m bands, depending on your setup.
  • Using 132ft wire, you may also access 160m 'Top Band' with an external AMU/ATU.

Versatile Installation

  • Suitable for straight, sloper, inverted V, inverted L, and other configurations.
  • Ideal for limited space and stealth applications.
  • Includes SO239 socket.

Power Handling

  • Capable of handling 1kW PEP SSB / 200W AM, Data, FT8, FT4 etc.
  • For SWR greater than 1.2, reduce TX power accordingly.

Multi-Band Functionality

  • Works on multiple frequencies; half-wave for 80m (~132 feet) translates to multiple half-waves on higher bands.
  • Adjust the wire length for specific frequencies between 3-30MHz.

Wire Length Calculation

  • Length (feet) = 468 / Frequency (MHz)
  • Length (meters) = 142.5 / Frequency (MHz)
  • Cut the wire slightly longer for tuning.

Installation Tips

  • Tuning depends on height above ground and nearby objects.
  • No radials required, usually no tuner needed.
  • For vertical use, a 4.2m (13.8ft) counterpoise at the lug next to the SO-239 connector is recommended.
  • Earth the coax braid at the rig end to prevent electrostatic discharge.

Cautions

  • If used with an external tuner, reduce power on bands with SWR above 1.2.
  • Avoid transmitting with high power or high SWR to prevent overheating and damage to the Unun, which voids the warranty.
  • *** IF THE UNUN MELTS - YOU HAVE USED IT WITH TOO MUCH POWER WITH A HIGH SWR & THE WARRANTY IS VOID ***

Accessories

  • See accessories for 50m length of Kevlar or M&P Dipoflex wire.

With this transformer, experiment with various setups to find the optimal performance for your location and requirements. Always remember, 'everything affects everything' when it comes to antennas.
