49:1 Hi Power Matching Transformer suitable for Multi Band End Fed Half Wave antennas
 
Ideal for home or field use
 
All you need to do is add your antenna wire - the Messi & Paoloni Dipoflex wire is ideal; See accessories
 
For example, if you attach 132ft of wire you will get 80, 40, 20, 15 & 10m
or 67ft of wire will give you 40, 20, 15 & 10m
Plus, if you use a AMU/ATU you MAY also get 30, 17 & 12m depending on your setup

*** When using 132ft wire, you will also get 160m 'Top Band' with an external AMU/ATU ***
 
Your wire may be straight, sloper, inverted V, inverted L etc
 
Ideal for limited space and stealth applications
 
SO239 Socket
 
Power handling 600W PEP / 150W AM & Data  -  50% TX/RX
 
Just add 1/2 wave wire to this transformer and tune the length to your preference.

Note that the antenna will be working on multiple frequencies.

Half wave for 80m (~132 feet) will be half wave on 80m and two half waves on 40m, four half waves on 20m, eight half waves on 10m etc... So there may be some gain on the higher bands.

If you want to use it on any particular frequency, just cut the half wavelength wire for that frequency or any frequency from 3-30MHz.

Wire length can be calculated by the following formulas:
  • Length (feet)= 468 divided by Frequency (MHz) or
  • Length (meters)=142.5 divided by Frequency (MHz)
Always cut a wire a bit longer to allow for tuning to your desired frequency.
Tuning depends on height above ground and nearby objects.
There are so many ways to install the wire so experiment away.

This antenna will not need radials and in most cases no tuner at all.

You can use it as vertical against good radial counterpoise.

4.2m (13.8ft) Counterpoise at the lug next to the SO-239 connector is recommended.

The Coax braid must be earthed at the rig end.
Long wires tend to collect electrostatic charge (usually when the weather is stormy) which can produce ESD (electrostatic discharge) at the end of your cable and damage your equipment.

If the transformer is used with an external tuner in conjunction with a single wire antenna, power should be reduced on those bands that show an SWR above 1.6 without the tuner.

Please do remember, as with all antennas, 'everything affects everything'
