My main home antenna is a homebrew end-fed wire. It is pretty much built according to the information from Steve Ellington’s YouTube channel. It uses a 134′ wire with a small compensation coil as detailed in this video. I love this antenna and switch effortlessly on all bands from 80m – 10m, except for 60m. This video nicely summarizes the design, but Steve’s channel has several longer, more detailed videos on this topic.
The 49:1 transformer is wound on three Fair-Rite 52 mix toroids that I got from DigiKey (no affiliation). They are super-glued together and then wound with #12 enamelled magnet wire that I found on Amazon. The capacitor, which I found on eBay, is 100pF and is rated to 10 kV. Although I don’t own an amp, I went heavy-duty on the construction and it should handle at least 500W on CW. Here is a nice video with very color-by-number instruction on winding the transformer, but please note that I went with 12 gauge wire and used a total of 14 turns (2 primary, 7 secondary) as specified in the notes on this video.
My installation consists of a 60′ run of LMR 400 that goes out of my shack and across the yard, ending under a large Sycamore tree. The transformer is mounted in a box about 3 feet above ground, with an 8′ ground rod right next to it. The wire is an inverted L, going up approximately 30′ then across the yard to a 30′ mast.
