The SIGMA Euro-Comm AM PRO HF Mobile 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. 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 Locked with Stainless Steel grub screw. 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 30cm (1ft) long Stainless Steel Whip that fits into the resonator ensures that
the Antenna works extremely well.
