- About products and suppliers:
Browse through the offers, check the specifications, and find a wholesale pc gps antenna or Ham radio antenna tower for sale by international suppliers. While each type has its own specifications and uses, all antennas serve the same function: to send and receive signals. The specific waveform with which they function has implications for the range and stability of the transmission. That’s the mechanism of an antenna in mobile communication. The UHF Satcom antennas, for example, operate with the Ultra High Frequency (UHF) waveform. This kind of wave operates by line of sight and ground reflection. They are popular in broadcasts and transmissions for TV, cellphone, Wi-Fi, Bluetooth, and GPS.
The pc gps antenna and other antennas all utilize a certain waveform. On a scale of frequency, at the top there's the UHF Satcom antenna, then the VHF communication antenna, and HF radio antenna types. The Very High Frequency (VHF) antenna uses waveforms with a lower frequency than the UHF Satcom radio antennas. This gives them a higher range, but they are still susceptible to blockage of the line of sight. The High-Frequency ones are used in long-distance communication, such as in an intercontinental transmission. They are popular in aviation, government, and amateur radio transmissions. An HF antenna aircraft setup is required for land-to-ground communication in trans-oceanic flights.
On Alibaba.com, you’ll find international suppliers for wholesale pc gps antenna and other types of antennas. Each of them with its own features. Search for the right antenna for your transmissions.
