Millimetrica has designed several antennas for special applications such portable logs, magnetic loops, collinear and parabolic prime focus reflectors. Most of this are custom design but usable for general purposes.
Find a list of the available project. Please contact Millimetrica at info@millimetrica.it for further information.

ANTENNA DESIGN
PORTABLE LOGs
Portable LOGs are logaritmic antennas for field measurement or "tactical purposes", where time and installation space are very limited, such to avoid using traditional antennas.
The main feature of the portable LOGs is the possibility to bend its elements on the boom, thanks to special metal joints like an umbrella structure.This allows the operator to "open" or "close" the antenna in a few seconds and to store it in a special tubular case.
Obviously the number of elements allowed by design is reduced and not comparable with traditional LOGs. For this reason the S.W.R. often is higher in some frequency segments, however because its excellent characteristics of portability and maneuverability, make it unique for field use.
Each antenna is delivered with a typ. Antenna Factor table, an SWR plot and a dielectric mast support.
We have two main design on VHF-UHF band customizable on other frequency ranges.
