LNA-WIDE-1
Wide band Low Noise Outdoor Amplifier
(No power cable is needed, the preamp is powered through the coaxial cable via power injector at the RX end of the
coax cable.)
Frequency range: 25-1300 MHz (at -6dB)
Gain 23 dB (typ.)
Input/output impedance 50 Ohm
Input/output connectors: F
Power supply voltage: 12 to 14V DC
(max. voltage limits 11 to 20V DC)
Current consumption: max. 80 mA
Noise figure: 3.0dB max.(typ.1.8 dB on 145 MHz, 2,5 dB on 500 MHz)
This LNA has been designed in order to improve weak signal reception in wide range of VHF-UHF frequencies.
(The LNA is not weatherproof. If you need the same LNA for outdoor use, please order LNA-WIDE-O).
Supply of power is universal, i.e. two methods can be used. 1. Separate cable for DC voltage or 2. supply via the
RF coaxial cable. Both methods are equivalent.
The LNA is protected against overvoltage and against voltage spikes resulting from static discharges during
thunderstorms.
LNA-WIDE-O has high linearity and high imd specs.
It is great for scanner and air-band enthusiasts, hams (2m&70cm bands) as well as professionals.
LNA-WIDE-O is designed for receive applications only, no T/R relay is present.
The combination of the LNA-WIDE-O and a double discone antenna result in an excellent active receive system
which has very few rivals.
