Vertical antenna A10 UHF is a collinear construction, based on 22 transposition half-wave elements. This is an extreme gain (10 times power gain) possible to achieve in such constructions. It has slightly narrower concordance and gain bandwidth, because of the sequential feeder circuit used, therefore some difficulties in generation of product line appear in lfrom production. That`s why such antennas now are manufactured only on demand.br>
