Transportable Delta Loop Antenna

The TDLS is a versatile multi-mode transportable antenna system.

Using multi-functional components, the TDLS consists of 2 tactical dipole antennas, covering 2-12 and 12-30MHz. The elements of these can be arranged as a directional wide band loop antenna, giving up to 7dbi forward gain. The system is supplied complete with all the necessary low loss feed cable, balun transformers, and ground anchors.

It is usual for the antenna to be erected on a tree, or suitable natural object, and, to assist mounting, SMC has a full range of complimentary support masts for use with the system. All components are either drab olive or matt black and the complete system packs into a single kit bag.
