Forestry Two-Way Radio System Buying Guide

Forestry is the hardest coverage problem we sell into. There is no building to wire, no repeater on the roof, and often no cell signal at the landing. A radio system for a logging crew, a silviculture contractor, or a tree-care company has to be planned around terrain and canopy first and features second, because a radio that cannot reach the other end of the block is not a radio, it is a paperweight.

Where two-way radio coverage fails in forestry

This is the section that matters most, so it comes first. Every other decision follows from it.

Forestry sites combine four coverage problems that rarely appear together anywhere else:

• No infrastructure. There is no existing repeater, no rooftop antenna, no wired backhaul. Whatever range you get on day one is what the handhelds themselves produce.
• Canopy attenuation. Dense, wet foliage absorbs radio energy, and it absorbs more of it as frequency goes up. A UHF system that works fine in a warehouse can lose a meaningful share of its usable range under a closed canopy, which is precisely why forestry has historically run VHF.
• Terrain shadowing. Ridges, draws, and steep side-slopes block line of sight outright. A crew half a mile away on the far side of a ridge can be harder to reach than a crew two miles away across a clear-cut.
• Patchy carrier coverage. LTE push-to-talk depends entirely on a commercial carrier's network. On remote harvest blocks and forest-service roads, that network is often simply absent.

Closed canopy and steep ground are the two conditions that decide a forestry radio system. Test coverage in the worst part of the block, not at the landing.

The practical consequence: do not buy the system, then discover the dead zones. Walk or drive the block with two demo radios before you commit to a band, a power level, or a fleet size. Test the worst spots deliberately, the bottom of the draw, the far corner of the block, the far end of the haul road, not the landing where everything works.

Is VHF or UHF better for forestry?

VHF, in almost every forestry case. VHF's longer wavelength diffracts better around terrain and is attenuated less by vegetation than UHF, which is why land-management agencies, logging contractors, and wildland operations have run VHF for decades. UHF's advantage, penetrating walls, floors, and steel, is an advantage forestry does not need.

Choose UHF only if you have a specific reason: an existing licensed UHF system you are extending, or a mill, shop, or office building where indoor coverage is the priority. If your work is genuinely split between a mill and the bush, that is usually two systems or a dual-band plan, not one compromise band.

Does LTE push-to-talk work in remote harvest areas?

Only where the carrier reaches. This deserves a blunt answer because the honest one costs us a sale sometimes.

The Motorola TLK110 and the in-vehicle TLK150 Mobile run on WAVE PTX over a nationwide 4G LTE network plus Wi-Fi. Where there is coverage, they are excellent for forestry: unlimited range between crews, no FCC license, no repeater to buy or site, and a dispatcher who can hear every block at once. For a company running crews across several counties, that is genuinely the right architecture.

Where there is no coverage, they do nothing at all. There is no fallback mode, no simplex "radio-to-radio" range when the network is gone. Check carrier coverage on the actual tract before specifying LTE radios, not at the shop, not in town, on the block.

The most common correct answer for a mixed operation is both: conventional VHF for on-block crew traffic that must work regardless of network, and LTE push-to-talk for supervisors, haul trucks, and office-to-field coordination on roads where carrier coverage exists.

What a two-way radio is not

Worth stating plainly, because forestry is high-hazard work and the wrong assumption here is dangerous:

Radios also do not replace your obligations under OSHA logging standards or your state and federal forest-practice rules. Treat the radio plan as one control in the safety plan, not the safety plan.

How many radios does a forestry crew need?

Count positions that must always be reachable, not headcount. A radio assigned to the faller, the skidder operator, the loader, the bucker, and the truck is more reliable than one assigned to whoever happened to be on shift.

Add spares. In the woods, a radio that is wet, dropped, or on a dead battery is out of service for the shift, and a crew that has to share is a crew that stops calling in.

Do forestry radios require an FCC license?

Yes, for the conventional VHF and UHF radios in this lineup. Business radios on FCC Part 90 frequencies, the R2, R5, R7, BPR50dX, and CM300d, require a license, and the radios must be programmed to the frequencies on it. We handle the paperwork and the programming together so the radios arrive ready to key up.

LTE push-to-talk radios such as the TLK110 and TLK150 do not need a frequency license, because they do not transmit on licensed radio spectrum, they need a service subscription instead. A repeater is licensed as part of the same Part 90 application, with its own transmit and receive pair.

When do you need a repeater?

When simplex, radio talking directly to radio, no longer covers the ground you work. That point arrives sooner in forestry than in almost any other industry, because terrain, not distance, is what defeats you.

Signs you have reached it: crews on opposite sides of a ridge cannot hear each other, the landing cannot reach the far corner of the block, or the haul road drops out halfway. Buying more handhelds will not fix any of those. A repeater sited on high ground will.

The Motorola SLR5700 is the workhorse for this: 1 to 50 W, 100% duty cycle, DMR Tier II, available in VHF 136 to 174 MHz. It can be tower-mounted at a fixed site or built into a portable, generator- or solar-backed configuration that moves with the operation, which is usually what a contractor working successive blocks actually wants.

A vehicle mobile at the landing is usually the cheapest way to extend a simplex system before you commit to repeater infrastructure.

A repeater is a system purchase, not a catalog purchase. Site selection, antenna height, feedline, power, and licensing all change the outcome. Talk to us before you buy one.

How should a forestry operation set up channels?

Separate traffic by function so routine chatter never sits on top of an urgent call:

• Falling and machine operations, the crew actively working the block. This channel stays clear.
• Landing and loading, loader, truck spotting, deck management.
• Haul and road, truck-to-truck traffic on active haul roads, including any road-use channel your operation or agency requires.
• Supervision and office, foreman, forester, dispatch. This is the tier that most often belongs on LTE.
• Emergency, monitored by everyone, used for nothing else.

Separating landing and haul traffic from falling operations keeps the channel that carries safety-critical calls clear.

Use CTCSS/DCS privacy tones to reduce interference from other operations sharing your frequency. Understand what they are not: privacy tones are not encryption. Anyone scanning the frequency can still hear you. If confidentiality genuinely matters, that is a digital encryption conversation.

What durability and battery specs actually matter in the woods?

• Ingress protection. IP55 is the sensible floor for crew radios; IP67, like the TLK110, is submersible and better suited to wet-coast or river work. Rain, sap, sawdust, and mud are constant.
• MIL-STD 810 drop and shock. Radios get dropped off machines, tailgates, and slopes. This is not a marketing line in forestry.
• Runtime. Shifts run long and there is no charger on the block. Look for 20+ hours and issue a spare battery per radio rather than a spare radio per crew.
• Audio in noise. Chainsaws and processors run 100+ dB. Noise-canceling audio (SINC+ on the R2, adaptive dual-mic on the R7) is the difference between a message received and a message repeated three times.
• Accessories. A remote speaker microphone on the shoulder strap outperforms a belt radio every time, because the radio never comes off the harness and the mic is next to your ear.

How to specify a forestry radio system

1. Map the ground. Blocks, haul roads, the landing, the shop. Mark where crews must be reachable and where they merely might be.
2. Test before you buy. Two demo radios, the worst spots on the block, on a bad-weather day if you can.
3. Pick the band. VHF unless you have an existing UHF system or a building-heavy operation.
4. Size the fleet by position, then add spares and spare batteries.
5. Decide the wide-area tier honestly, repeater, LTE, or both, based on measured coverage rather than on the map.
6. License and program together so the radios arrive working.
7. Write the channel plan and the check-in procedure before the radios ship, and train to it.
