Reduce Both Installation Time AND Drilled Holes in Your Roof

Reduce the number of antennas on the roof of your vehicle with the new dual-port antenna from STI-CO.  The integrated coupler on this antenna provides two ports for separate VHF and 700 MHz mobile radios, giving you simultaneous two-band operation.

This antenna offers Superband performance, covering the entire 150-174 MHz bandwidth, and from 760-870 MHz for the 700 MHz radio. It fits any standard NMO mount for an easy and less expensive installation.

Plug-and-Play Antenna Works With Portable Whip

This amazing new STI-CO plug-and-play mobile magnet mount antenna operates with the whip from your portable radio!  It accepts any whip with a flush female SMA (SF) connector and instantly adapts to your specific frequency anywhere between 100 MHz and 1000 MHz. The easy-to-install antenna suits either temporary or permanent requirements and enhances your portable’s performance.

This antenna base includes 17 feet of RG316 feed line and your choice of connector. You may purchase the base alone or with the portable radio whip, available in VHF, UHF or 800 MHz.

Covert VHF Bumper Antenna

The new STI-CO covert VHF Bumper Antenna is completely hidden behind the front and rear bumpers of the vehicle and performs better than similar styles on the market! This diversity antenna covers the entire 136-174 MHz frequency range, subject to installation site factors such as available air space and proximity to metallic structures. It is easy to install using the super-strong adhesive tape provided. The system includes two antenna elements, mounting tape, two feed lines, and connectors of choice.

Rugged 220 MHz Train Antenna

The new 220 MHz Train Antenna provides up to five times more bandwidth than other low profile antennas on the market. Wider bandwidth reduces detuning from harsh environmental conditions such as snow and ice that commonly occurs with narrow band antennas. The new rugged cast aluminum design not only makes it virtually indestructible but also filters out noise induced into the communication system.

Unbreakable Flexi-Whip and Rugged Low Profile GPS in One Antenna

Unbreakable Flexi-whip and rugged GPS low profile in one antenna. Now there is one less antenna to install on your vehicle. The Flexi-whip mast is guaranteed not to break and is field tunable for VHF, UHF, 700 or 800 MHz. The GPS housing and die-cast base will survive the harshest conditions. The solid brass NMO components give optimal conductivity and the Retro-fit GPS base will work with any standard 3/4” portable antenna.
