End Fed Half Wave (EFHW) Antenna High Power 400w SSB 250w CW/Data49:1
This antenna is an excellent choice for an efficient, High Power End Fed Half Wave (EFHW) for your home QTH where you need an SO-239 coax connector.
Built using a two T240-43 Fair-Rite 2643803802 cores, 49:1 winding, 3kv 100PF TDK capacitor and all stainless-steel components. The antenna is built to last.
We can supply the antenna as a transformer only, or with 80m or 40m band antenna wire options.
Select 80m band option to resonate on 80m, 40m, 20m, 15, and 10m with no ATU.
You can also use the antenna on 30m, 17m and 12m bands, although you may need to use an ATU.
Select 40m band option to resonate on 40m, 20m, 15, and 10m with no ATU. You can also use the antenna on 30m, 17m and 12m bands, although you will need to use an ATU.
