PWR-NR770H
The NR 770H antenna is a dual-band antenna designed to operate in the VHF (144 MHz) and UHF (430 MHz) frequency bands. Here are the key features of this antenna:
VHF-UHF Frequency Bands: This antenna is capable of transmitting and receiving signals in two different frequency bands: VHF (144 MHz) and UHF (430 MHz). This makes it versatile for use in mobile radios and other communication devices that operate in these bands.
200W Maximum Power: The antenna can handle a maximum transmit power of up to 200 watts, making it suitable for high-power radios and transmitters.
Gain of 2.15 dBi in VHF and 5.5 dBi in UHF: The antenna has different gains in the two frequency bands: 2.15 dBi in the VHF frequency band and 5.5 dBi in the UHF frequency band. This indicates its ability to concentrate antenna radiation in a specific direction, thereby improving the efficiency of signal transmission and reception in both bands.
PL Male Connector: The antenna is equipped with a PL male connector (PL-259), which is a radio frequency connector commonly used in communication equipment.
102cm Length: With a length of 102cm, this antenna is moderate in size and suitable for installation in vehicles or other locations where a longer antenna is needed to improve radiation performance.
50 Ohms Impedance: The antenna has an impedance of 50 Ohms, which is standard in radio communication systems.
170g Weight: The antenna is relatively lightweight, making it suitable for installation in vehicles and other mobile applications without adding significant load.
NR 770H is a dual-band antenna that offers efficient performance in the 144 MHz (VHF) and 430 MHz (UHF) frequency bands. Its ability to handle up to 200 watts of power and its different VHF and UHF gains make it suitable for a variety of communication applications, including amateur radio and in-vehicle mobile communications. Its length of 102 cm is suitable for efficient operation in both frequency bands.
