Finally got the Butternut (HF9V) antenna installed. It's been over 2

Butternut Hf9v. Butternut HF9V Vertical As A Ham Radio ALE Antenna HFLINK, 52 OFF Butternut HF-9V vertical antenna operates on nine bands 80m through 6m with single, highly efficient vertical radiator of only 7.9m (26ft) On 10 meters the HF9V becomes a 3/4 l radiator with considerably greater radiation resistance and efficiency than 1/4 l trapped types.
Butternut HF9V Vertical Antennas work nine popular bands--80 through 6 meters--with an extremely efficient vertical radiator that's only 26 ft On 10 meters the HF9V becomes a 3/4 l radiator with considerably greater radiation resistance and efficiency than 1/4 l trapped types. The HF9v is designed with large diameter tubing for the coils that enhances overall performance, The bandwidth is very narrow on 80 meters which is to be expected given the 26 ft tall radiator
KJ6YVT Butternut HF9V 806 Meter 9Band Vertical. but for 9 bands: 80, 40, 30, 20, 17, 15, 12, 10 and 6m The Butternut has been optimized directly on the roof with SWRV close to 1:1 in all bands by means of an MFJ analyzer at the base, acting on the physical element-inductance length and with the "cut & try" method for adjusting the wire counterpoise elements .
BUTTERNUT HF9V 9BAND 80, 40, 30, 20, 17, 15, 12, 10 & 6m VERTICAL. I did work JA's on 80 meters from the east coast which for a simple vertical is quite a good QSO. The feed point impedance is a nominal 50 Ohms, matching line and RF connectors included
