Grazioli HW20V Vertical Antenna for 20m Band ****
Vertical Antenna for 20m band (14MHz)
HW20V by Grazioli antenne is a 1/2 vertical antenna of heavy duty
constructions for use in the amateur 20m band (14MHz). We have created a
unique antenna, highly performing for lovers of the 20m band, the vertical
whip is half-wave long (only the radiant part is 10.13m) powered at the base,
HW20V takes up the operating principle of the younger sister HW10V wich works
in the 10m band, and which has given many satisfactions to our customers. This
antenna can be installed both on the ground and on the roof with a pole of
only 2 or 3m, it covers the entire 20m band with SWR below 1.5, these
caracteristics make HW20V probably the best antenna available for the 20m
band. Relatively light, only 5.4Kg, it can also be used in portable
installation (QRP), despite its height it does not require special attention
when it is hoisted vertically, the final tuning is carried out comfortably at
the base by adjusting the coaxial capacitor placed at the side of the coil.
Like all our products is made with the best materials available today, the
telescopic tubes are made in Italy on our specifications and precision drawing
in AW6063-T66 alloy and machined with latest generation LASER and CNC
machines, all the fixing part and clamp are made in AISI-316 stainless steel,
the screws and the UBolt are in AISI-304 Stainless steel.
(In stationary use, is recommended to guying the antenna with non-conductive
cables or rope using the supplied guying clamp)
