EFHW Antenna 49:1 Transformer



This is a hand made EFHW Antenna with a built in 49:1 Transformer. This is incredible for POTA, SOTA and other portable/field operations. Setup in any end fed configuration you like.

Please let me know if you are interested in a different configuration. With wire, without, 20m band, 40m band, etc. I can look at offering different configuration if there is interest.

The Winder is Printed in ASA and can handle the elements but is not intended for long term or permanent outside installation.

The Ferrite Toroid is a F140 43 mix, size 23mm inside dimension by 35.55mm outside dimension and 12.7 tall. This is beefy for the application, a bit excessive for 100w SSB and at 50w digital, minimal heating effect was noticed during operation.

If you order with Wire, you get No 26. Poly-Stealth Antenna Wire length for the band selected and a clip for the end. This is high quality, barely visible wire. Wire length is longer allowing you to trim to the portion of the band you like or simply fold it back at the end.

Select "Assembled 40m Wire" for a fully assembled wire winder with 68' (long for 40m band) of wire and an S clip, Ferrell and heat shrink if you want to put a loop on the end.
Select "Assembled 20m Wire" for fully assembled cut to 34', again long for the band for you to trim as desired.
Select "Assembled No Wire" for the fully assembled toroid assembly with BNC connector.
"Kits" are NOT assembled, you get to have the fun.
Per request, "Toroid +Winder..." is just the winder and a toroid with no wire winding.
Select "Winder only" for just the winder.

Please note the end of the wire is not terminated with a loop as shown in the photo. If selection is made with wire, a ferrule, heat shrink and clip is included to terminate the end after trimming length to desired frequency and SWR match by the user.
