Radio Towers Around Kirksville: What Are They Used For?

A tower is the structure that holds communications equipment. The antennas mounted on it are the parts that actually transmit, receive or relay radio-frequency signals.

That distinction explains why looking at a tower from the road rarely tells you exactly what it does.

A single site can support several services at once.

Common uses for towers around a regional city

Communications towers around Kirksville can support systems such as:

• AM, FM or television broadcasting;
• cellular networks;
• public-safety communications;
• amateur-radio repeaters;
• microwave or other point-to-point links;
• business and utility communications.

Some towers are built for one primary service. Others host antennas belonging to multiple organizations.

The presence of several antenna shapes on one structure does not necessarily mean they all belong to the tower owner.

Tower shape is not reliable identification

People often try to identify a tower by whether it is guyed, self-supporting or monopole-style.

Those shapes tell you something about the structure, but not enough to identify the service with confidence.

A tall guyed tower may carry television broadcasting, FM broadcasting, microwave antennas and other tenants. A monopole may carry cellular antennas, public-safety equipment or both.

Even antenna shape can mislead a casual observer because many radio services use similar-looking vertical, panel, dish and directional antennas.

The safe rule is:

use licensing and owner records, not visual guesses.

A verified local example: the KTVO site

KTVO is a licensed television station serving the Kirksville market, and FCC/registration records identify a KTVO-associated tall broadcast structure in the region near Hitt, Missouri.

That site is also useful because it demonstrates tower sharing.

The current RepeaterBook record for the W0CBL 145.130 MHz amateur-radio repeater places that repeater at the "KTVO Tower" in Adair County. The record identifies NEMOARC as the sponsor and lists the system as active/open.

That does not mean the amateur repeater owns the tower. It means amateur-radio equipment is listed at a site whose primary identity is associated with a television broadcaster.

For the repeater itself, see The W0CBL Amateur Radio Repeater in Kirksville.

Broadcast towers and studio buildings are not the same thing

A radio or television station's office or studio can be miles from its transmitting antenna.

That is especially important when looking at regional television facilities. A station may identify with Kirksville while its high-power transmitter sits outside the city where terrain, height and spacing work better for regional coverage.

Likewise, an FM station's business address does not necessarily tell you where its transmitting antenna is mounted.

How to identify a tower properly

For a specific structure, useful records include:

• FCC broadcast-station records;
• FCC Antenna Structure Registration records where registration is required;
• station-owner information;
• frequency-coordination records for amateur repeaters;
• official agency pages when the site is publicly documented.

Even then, a record may identify the registered structure or a licensed station without listing every tenant using the site.

That is why a responsible tower guide should stop short of claiming that every antenna visible in a photograph has been identified.

Why this matters beyond curiosity

Knowing how tower sites work helps explain why communications coverage is uneven.

Height can extend line-of-sight radio coverage, but signal range still depends on frequency, transmitter power, antenna pattern, terrain, receiver location and interference.

A visible tower on the horizon does not guarantee that a particular service comes from it, and being close to a tower does not guarantee that your phone, scanner or amateur radio is using equipment on that structure.
