About Comtelco

A Legacy Rooted in Two-Way Radio

Comtelco traces back to 1982, when three former Motorola employees founded Whisco Component Engineering to design, develop, and manufacture products for the communications market. Comtelco began as a division distributing Whisco’s designs and grew into Comtelco Industries, a wholly owned subsidiary selling antennas worldwide from its plant in Glendale Heights, Illinois.

In 2017, Mobile Mark acquired Comtelco Industries. The two lines complemented each other, with Comtelco’s two-way radio antennas extending Mobile Mark’s coverage into low band, VHF, and UHF frequencies. Comtelco’s antennas, equipment, and personnel moved a few miles down the road to Mobile Mark’s facility in Itasca, Illinois, keeping production local and the Comtelco name on the product. The company’s long-standing focus on customer satisfaction carried over too.

The Comtelco Product Line

What Comtelco Antennas are Known For

The Comtelco line covers mobile, base station, and directional antennas for two-way radio and wireless systems, along with a variety of mounts and accessories to fit your deployment requirements.

Base Station Antennas

Omnidirectional center-fed dipoles with copper alloy elements sealed in UV-inhibited fiberglass radomes. A drain system clears condensation from temperature swings, and heavy-duty and super-duty diameters add strength for demanding sites and low-band operation.

Yagi Antennas

Comtelco’s cold-weld process presses solid elements into precision-machined booms with more than 1,000 lbs of hydraulic pressure, then seals the antenna in epoxy powder coat. The result is as rugged as a welded Yagi at a lower cost. Fully welded, enclosed-feed models were designed to meet positive train control requirements.

Folded Dipoles

Folded dipoles work as omnidirectional or directional antennas and generally cover wider bandwidths than other dipole designs. Self-contained models include an integrated mast, while bolt-on elements install on a customer-supplied mast.

Spring-Loaded Mobile Antennas

Known as the leader in spring-loaded antennas, Comtelco introduced the first spring-loaded contact in a mobile antenna. Standard base-loaded models use a .125-inch tapered stainless steel whip that resists bending on a moving vehicle, and most black whips are powder coated so they won’t chip or flake. Options run from low band through 800 MHz, plus multiband and low-profile designs

Panel & Ceiling Mount Antennas

Panel antennas focus signal on a specific area as a compact alternative to higher-gain directional antennas. Ceiling mount and tamperproof models handle in-building coverage, with ground planes included where the surface can’t provide one.

Mounts & Accessories

NMO, magnet, trunk, and specialty mounts, plus couplers, diplexers, triplexers, surge protection, and custom cable assemblies. An all-brass NMO mount with no flats avoids cross-threading, and its stainless steel piercing saddle makes a solid electrical and mechanical connection.
