Screwdriver antenna basic
A Screwdriver is a motorized antenna that extends and retracts, shorting a coil, which adjusts the length of the antenna as it is tuned
BigIR assembly

BigIR MK III Vertical with 80 meter coil
The antenna does well on all bands including 60 meters. The SWR is low enough that I don't need to use the antenna tuner
Butternut HF2V 40/80 Meter Vertical
I bought this antenna used, but in new condition, at the moment I'm using 40 radials 11 meters long
