Frequently Asked Questions

Q: Is the RH771S BNC antenna compatible with my Kenwood TK-series radio?

A: Yes! The RH771S is compatible with many popular Kenwood TK-series radios including the TK100, TK200, TK220, TK300, TK310, TK320, TK308, TH28A, and TH42AT — as long as your radio uses a standard BNC connector. Always verify your radio's connector type before ordering.

Q: What is the difference between the RH771S and a standard stock antenna?

A: The RH771S offers improved gain (2.15 dBi at 144 MHz and 3.0 dBi at 430 MHz) over most factory-included antennas, meaning better signal range and clearer reception. Its flexible soft design also makes it more durable and comfortable to carry compared to rigid stock antennas.

Q: Can I use this antenna for both VHF and UHF frequencies?

A: Absolutely. The RH771S is a dual band antenna covering both 144 MHz (VHF) and 430 MHz (UHF), making it ideal for radios operating on two-meter and 70-centimeter amateur radio bands, as well as compatible commercial handheld radios.

Q: Is the RH771S antenna flexible or rigid?

A: The RH771S is a soft, flexible antenna approximately 40 cm (15.74 inches) long. Its flexible design helps prevent breakage from accidental bending and makes it easier to use in the field.
