SIGMA  AM-PRO  20 Meter HF Antenna

Specifications

●    Power handling 250 watts

●    Length  2.40m (Approx)

●    Impedance 50 Ohms

●    Frequency 14 MHz

●    SWR 1.5:1

●    Whip 17.7 ph stainless

●    Fitting 3/8 UNF

●    Made in Great Britain

The SIGMA Euro-Comm AM PRO HF Antenna Range are High Quality, Heavy Duty, Slimline Construction Antennas for the purpose of HF Amateur Radio Bands. There are 11 models in our range, starting from 4m, right up to 80m. They are designed to operate on the phone portion of the Band, Bandwidth and VSWR. The VSWR may vary according to the mounting location. VSWR at resonance should be 1.5:1 or less when properly matched. The Whip is Field Tunable for lowest VSWR Double Locked with Stainless Steel grub screws. If you require a greater bandwidth, an ATU may be required. Heavy gauge Copper wire is used in the construction of the resonator, and is wound onto a fibreglass mast, and finished in Sleek Black. The fittings are of Brass construction and the 1.2m (4ft) long Stainless Steel Whip that fits into the resonator ensures that the Antenna works extremely well.
