Quick Answer: UHF (462-470 MHz) is better for indoor use and urban environments because shorter wavelengths penetrate walls and buildings more effectively. VHF (136-174 MHz) is better for open outdoor terrain and longer distances in flat land. Most consumer walkie talkies use UHF. FRS and GMRS radios operate on UHF at 462-467 MHz. You’re looking … Read more
Quick Answer: Walkie talkies use three main frequency bands: FRS/GMRS on UHF 462–467 MHz, CB radio on HF 27 MHz, and ham radio on VHF/UHF bands. Most consumer walkie talkies are FRS and require no license. GMRS needs a $35 FCC license but offers better range. CB radio uses 40 channels and also needs no … Read more
Quick Answer: CB radios operate on 40 channels between 26.965 MHz and 27.405 MHz. Channel 19 is the main trucker highway channel. Channel 9 is the emergency channel. No license required for CB radio in the US or UK. CB radio runs across 40 designated channels in the 27 MHz band — and every single … Read more
CB radios reach 1 to 5 miles on flat ground in AM mode — not the 50 miles on the box. That figure is atmospheric skip propagation, which only happens under specific ionospheric conditions. SSB mode on a properly tuned antenna with a ground-plane mount gets you the best real-world range. In a city or … Read more
Quick Answer: FRS uses 22 channels on 462–467 MHz. No license required for FRS. GMRS uses the same frequencies but with higher power — requires a $35 FCC license. Channels 1–7 and 15–22 are shared between FRS and GMRS. Channels 8–14 are FRS only at 0.5W max power. Most people grab a pair of walkie … Read more
