Dual-band SMA antenna for handheld radios
The NA-805 SMA-female antenna connects directly to compatible handheld transceivers including Baofeng UV-5R series, Linton LT models, Puxing, Weierwei, Wouxun and Quansheng radios. It operates across 144, 430 and 1200 MHz bands with a stated gain of 2.15 dBi and maximum power handling of 10 W. The connector fits SMA-female ports on the listed devices.
Passive thermal and power profile
As a passive antenna the NA-805 produces no noise and draws no power from the radio. VSWR is specified as less than 1.5 across the supported bands, indicating efficient power transfer without additional heat generation. Physical dimensions are approximately 45 by 12 mm, adding minimal bulk to the handheld unit during normal operation.
Single-item package with no software
The box contains one NA-805 SMA-female antenna and no cables, adapters, mounting hardware or configuration software. All listed compatibility relies on the radio having an SMA-female connector and operating within the stated frequency ranges. Buyers needing a different connector type, higher gain or additional accessories will need separate purchases.

Questions about this item
How do I install the NA-805 antenna on my Baofeng UV-5R, and what is the common mistake?
Screw the SMA-female connector onto the radio's SMA-male port by turning the antenna base only; do not twist the flexible whip or you will damage the internal coaxial joint.
What maintenance will the NA-805 antenna need over time?
Inspect the SMA-female threads and the rubber whip for cracks after heavy use; wipe the connector with a dry cloth if corrosion appears, otherwise no routine service is required.
What limit appears first when I transmit at 10 W continuously with this antenna?
The 1.5 V.S.W.R. limit is reached first, reflecting power back into the radio and causing it to heat up or fold back output before the 10 W rating is exceeded.
