Aerials
The only aerials that TW produced (or investigated producing) were
Halos for the 2m band. For the uninitiated, a Halo is just a half wave
dipole with the 'legs' bent in the shape of a circle (the ends do not
meet) and is fed with coax via a gamma match . I am led to believe that
Halo stands for 'HAlfwave LOop, but strictly speaking it is not a loop
antenna. The Halos were intended for mobile use
(horizontal polarisation) but as they were omnidirectional
aerials, many people (including me) also used them as fixed station
aerial. One of mine was fastened to a chimney on a 3 storey
building
at my original /A location in Ormskirk while the other was
on the roof of my 'Moggy 1000 van' (see photo in the Introduction
section).
