The Sigma compact centre load antenna complete with magnetic base, coax cable and PL 259 connector, all ready to go with easy tune preset SWR whip markings.

The top whip has one SWR guide mark for both EU and UK bands making it very simple to tune.

An SWR meter should still however be used to fine tune the antenna.

The magnetic base has a protective boot and the whole antenna stands only 28" [70cms] high

This antenna will not perform as well as the larger CB aerials, but it is very useful for those who need a more compact aerial.


Specifications

  • 1/4 wave base loaded mobile antenna
  • Power Handling 100 watts
  • Length 0.78m
  • Coil length 140mm
  • Coil diameter 8 mm
  • Impedance 50 Ohms
  • Frequency 27-28 Mhz
  • SWR 1:1.5
  • Fitting 3/8 UNF
  • Whip: 17/7 ph Stainless Steel
  • Made in Great Britain
  • Antenna average range 4 miles

Is this any good? I'm currently using a magazine holder as my aerial. Although it gets me perfect signal, it looks rather odd hanging on the window's handle. 32980767-AB1ls.jpg

What a waste. lol
One-four for a copy............

On the side, slide.
Sigma were a known brand in the 80's if this is still the same company. Centre loaded is more efficient than base loaded but not so aerodynamic. I had one similar to this years back and it performed alright. Would prefer a radial length of at least 1m but ok for limited space Also had a KT40, DV27, Dial-a-Match and cherokee half breed to name a few for those of you that remember.

Would this make a good aerial for a scanner?

Only for scanning the 27Mhz band. For multiband scanning depending on the frequencies required you would need something like a Discone antenna.
