Hytera PD402i DMR Digital Portable Two-Way Radio (VHF 136–174 Mhz)

The PD402i VHF is a no-display radio — the right tool for workers who need to communicate and get back to the task in hand. Construction crew leads, groundskeeping supervisors, yard managers, and outdoor security staff don’t need a menu system on their radio. Two programmable side buttons, a channel selector knob, and a PTT cover everything an outdoor worker does with a radio during a shift. The tactical buttons allow no-look operation even in work gloves, wet conditions, or low-light environments.

VHF at 136–174 MHz propagates farther over open ground than UHF under comparable conditions. The longer wavelength follows terrain contours, clears low vegetation, and reaches across parking lots, construction yards, and open campus grounds with less signal loss. At 5W — one watt more than the UHF variant — the PD402i VHF delivers coverage that spans a construction site perimeter, a school campus with multiple buildings, or a transportation depot yard in a single talk channel without a repeater. For operations spread across acreage rather than floors, VHF is the practical default.

The 1500mAh Li-ion battery runs 16 hours in digital mode at a 5-5-90 duty cycle. An outdoor crew that starts at 6AM and works through a 10-hour shift carries one charge for the full day with time to spare. The optional 2000mAh battery extends runtime to 22 hours in digital mode — relevant for two-shift operations at construction sites or transportation hubs where battery swap logistics are difficult to manage during active work.

For large campuses spanning multiple buildings or zones, the PD402i supports DMR Tier II repeater infrastructure. Roaming lets workers move between coverage zones — from the job trailer to the far end of the site — without losing calls mid-transmission. Pseudo-trunking allocates calls across both DMR timeslots on a single channel automatically, which matters on sites with large crews where radio traffic peaks at shift start and handover times.

The PD402i VHF carries an IP55 rating confirmed by Hytera US, providing protection against directed water jets and dust ingress. On outdoor sites, this covers rain exposure, mud, dust from ground work, and direct water contact from equipment washdowns. Both programmable buttons support emergency alarm configuration: one press sends an alert with the radio’s ID to the dispatcher and other designated units — critical for lone worker safety on construction sites and transportation yards where workers often operate outside direct line of sight.

Operation of the Hytera PD402i VHF on licensed frequencies in the United States requires an FCC Part 90 license. This applies to commercial and business radio use across construction operations, facilities management, transportation, education campuses, and outdoor security teams operating on private licensed VHF frequencies in the 136–174 MHz band.

As an authorized Hytera dealer, AXDIGITAL assists customers throughout the licensing process — from identifying the correct VHF frequencies for your site to preparing and submitting the FCC Part 90 application. VHF is the recommended band for outdoor open-area operations and low-density building environments; our team provides guidance on frequency selection based on your terrain, site size, and existing equipment.

The PD402i-V1 is FCC Part 90 certified. For organizations operating across large outdoor sites or multiple campus buildings, we provide frequency coordination recommendations to prevent channel interference.
