End Fed Half Wave Antenna Transformer 49:1 Genuine Fair-Rite FT-240-43 Toroid. Condition is New.
NOW OVER 4000 SOLD!
I have been a Ham Radio operator for 62 years and enjoy antenna building. I am the builder of this transformer and have tested it extensively on 40, 20, 15 and 10 meters.
This size is designed for your standard 100 watt transceiver. It utilizes the larger FT-240-43 Toroid. (See my other listings for the lower power version)
I have a 66 foot end fed antenna that I'm using and have found the SWR across all 4 bands to be 1.5:1 or less! (using MFJ 259B analyzer) Every transformer I sell has been individually tested to make sure it meets my expectations. I have performed dozens of signal comparisons with my full size G5RV and in the majority of the cases the EFHW was the winner.
You can, of course, also use this on 80 meters with a 132 foot wire if desired. It has been my experience that connecting only the antenna wire and nothing else works very well! No Ground, No counterpoise, No Common Mode Choke, only the coax and antenna wire. For permanent installations you may want the ground for lightning protection. I personally am using 50 feet of RG8X which works fine. Remember that the coax is part of the antenna, so don't make it too short. (I suggest 25 feet minimum!)
I have been selling these for 5 years now and have over 4000 units in operation. If you are in any way dissatisfied with this product just return for full refund (minus shipping). Size is roughly 4" X 3.25" X 1.5". Weight is about 10 oz.
For references, just Google "TennTennas" and you will find plenty of videos and comments on my transformers.
Note: The labels on the box in the photo (antenna etc.) were added over the photo for clarity. They are not on the actual transformer box.
Check out these videos to see the transformer in actual use!
