What is the difference between the UHF and VHF?
The difference between the UHF band and the VHF band of the walkie-talkie is: the frequency is different, the diffraction ability is different, and the applicable area is different.
First, the frequency is different
1, UHF band: The frequency of the UHF band is relatively high to the frequency of the VHF band, and the penetration is better.
2, VHF band: The frequency of the VHF band is relatively low to the frequency of the UHF band, and the penetration is worse.
Second, the diffraction ability is different
1. UHF band: The diffraction ability of the UHF band is relatively poor than the diffusion property of the VHF band.
2, VHF band: The diffraction ability of the VHF band is better than the diffraction ability of the UHF band.
Third, the applicable area is different
1, UHF band: Applicable area for the UHF band is more suitable for urban areas.
2, VHF band: Applicable area of the VHF band is more suitable for the plain area.
The UHF Omni Antenna internal & external antennas are manufactured by C&T RF Antennas Inc, the RF antenna manufacturer in China. We provide UHF&VHF Antennas with indoor & outdoor antenna types.

How to mount the Indoor Ceiling Antenna?
Installation instructions:
1. installation tools: hand drill, spanner
2. Installation steps.
Select the position of the antenna and drill a 25mm diameter hole in the ceiling with a hand drill as shown below.
Fasten the antenna to the ceiling with the fastening nut, the thickness of the ceiling should not exceed 22mm.
3. Notes.
a. When installing the antenna, pay attention to the hole diameter control at 25mm, not too big or too small.
b. The antenna should be hung flat.
c. After the connection is completed, seal the antenna with waterproof tape.
