Frequently Asked Questions
Q: Is the Nagoya NA-773 antenna compatible with the Baofeng UV-5R radio?
A: Yes! The Nagoya NA-773 is specifically designed to be compatible with the Baofeng UV-5R, UV-5RE, BF-888S, and many other handheld two-way radios that use an SMA-Female (SMA-F) connector. Always verify your radio's connector type before purchasing.
Q: What is the benefit of a telescopic antenna over a standard stubby antenna?
A: The telescopic design of the NA-773 lets you adjust the antenna length depending on your environment. Extending it to 34.5 cm increases signal gain and range, while collapsing it to 11 cm keeps it compact and portable. This flexibility makes it a significant upgrade over fixed-length stubby antennas.
Q: What frequencies does the NA-773 dual band antenna support?
A: The NA-773 supports dual band operation on 144 MHz (VHF) and 430 MHz (UHF) — the two most common frequency bands used by handheld amateur and two-way radios. It offers 2.15 dBi gain and handles up to 50 watts of power.
