Product Overview
Kenwood KRA-15AM3 flexible whip antennas tuned for 403-430 MHz UHF low band operation. OEM replacement parts for the TK-290 and TK-390 series handheld transceivers — the frequency range associated with licensed government and public safety channels. The AM3 suffix identifies this as the UHF low band variant, distinct from the KRA-15AM (440-490 MHz) and KRA-15AM2 (470-520 MHz). Using the correctly tuned antenna avoids high SWR conditions that can damage a radio's power amplifier. The KRA-27M3 is the listed current replacement for this discontinued model — these are legacy OEM units.

Frequently Asked Questions
Which Kenwood radios are these antennas designed for?
Designed for the TK-290 and TK-390 series operating in the 403-430 MHz range. Compatibility with TK-3140, TK-3180, NX-series, or other models depends on connector type and programmed frequency — verify your radio's antenna port and frequency range before ordering.
What connector does this antenna use?
Not confirmed — available sources conflict on this point. One reference indicates SMA-Female; another references a threaded stud connector associated with TK-390 series radios. Verify the connector type against your specific radio model before ordering. Do not assume compatibility.
Can this antenna be used on standard commercial UHF frequencies like 460 MHz?
No. This antenna is tuned for 403-430 MHz. Operating it outside this range produces high SWR, which reduces range and can damage the radio's transmitter. For 440-490 MHz use the KRA-15AM; for 470-520 MHz use the KRA-15AM2.
Is there a current production replacement for this model?
Yes. The KRA-27M3 is the listed current replacement for the discontinued KRA-15AM3.
Seven units in hand means one procurement covers a fleet — no back-ordering individual antennas when the next radio comes in for service.
