Hytera AN0445H03 UHF Stubby Antenna for TC-508 / BD502i / PD502i Series
Hytera AN0445H03 is the OEM UHF stubby antenna for a wide range of Hytera portable radios, including the TC-508, TC-610, BD502i, BD552i, BD612i, PD502i, PD702i, and HP682 series. It uses an SMA female connector and operates across the 420–470 MHz band. At ~9 cm, it keeps the radio profile low for comfortable belt carry throughout a full shift.

Why Professionals Choose the Hytera AN0445H03
A broken or missing antenna doesn't just degrade signal — it takes a radio offline entirely. For security teams, warehouse supervisors, and field crews running Hytera BD or PD series radios, replacing a damaged antenna quickly with the correct OEM part matters. Using the wrong antenna — wrong frequency, wrong connector type — can result in poor transmission, port damage, or an FCC compliance issue for licensed UHF operations.
The AN0445H03 is designed specifically for the UHF range of 420-470 MHz. It uses an SMA female connector with a standard thread pattern matched to the BD502i, BD552i, PD502i, PD702i, HP602, HP682, and other Hytera portables in that lineup. At approximately 9 cm, it's a stubby form factor — shorter than a standard whip, which matters when radios are worn on the belt or inside a jacket. A long whip antenna on a belt-mounted radio catches on doorframes, safety equipment, and vehicles. The AN0445H03 eliminates that friction without sacrificing UHF coverage for typical indoor-to-outdoor commercial distances.
Stubby antennas trade some gain versus a full-length whip — that's a physics reality. But for most commercial deployments where radios work within a building complex, a warehouse, a campus, or a port terminal, the difference in practical range is minimal and the ergonomic benefit is immediate. Operations managers running 10–50 radios typically stock AN0445H03 as a field-replaceable part because replacements happen fast and downtime stays short.
AXDIGITAL supplies the AN0445H03 as an authorized Hytera dealer. All units are genuine OEM parts — not third-party replicas with unverified tuning or non-standard thread pitch that can cross-thread the antenna port on the radio body.

FAQ
What is the difference between the AN0445H03 and the AN0445H01?
Both antennas cover the same 420–470 MHz UHF band and use an SMA female connector. The AN0445H01 is the standard whip supplied with the radios. The AN0445H03 is the shorter stubby version — same compatible radio list, shorter physical profile. Hytera confirms the AN0445H03 can be used as a direct replacement for the AN0445H01 when a compact form factor is preferred.
Will the AN0445H03 work with my Hytera DMR digital radio?
Yes — if your radio is on the verified compatibility list. The AN0445H03 works with Hytera analog and DMR digital portables that use an SMA female connector and operate in the 420–470 MHz UHF band. Verified US-market models include BD502i, BD552i, BD612i, PD502i, PD702i, PD782i, PD982i, HP602, and HP682. Contact us if you need to confirm a specific model.
Does a stubby antenna reduce communication range compared to the standard whip?
In open-air conditions, a stubby antenna has marginally less gain than a full-length whip. In practice, for commercial deployments inside buildings, warehouses, port terminals, or campuses, the difference in working range is not operationally significant. The trade-off is a smaller physical profile that reduces wear on the antenna port and improves comfort for personnel wearing the radio on a belt throughout a shift.
