In low-cost RF applications a whip antenna generally provides the best
overall performance. In many cases, however, the use of a whip is not
practical for cost or cosmetic reasons. In instances where a designer is
looking for a blend of easy concealment, low cost and good
performance, a helical antenna is usually the optimum choice. The HE
series from Linx delivers exceptional performance and ease of use,
while maintaining a cost factor appropriate for high-volume
applications. Linx helical antennas are precisely wound and matched to
provide the lowest possible SWR at the operational frequency. In
addition, the antenna diameter and inter-coil spacing are optimized to
provide a wider than typical bandwidth.
