Ultra low noise onboard amplifier with gain from - 9 dB to + 18 dB:
Inbuilt ultra low noise amplifier allows antena usage in the situations with variable coaxial cable length from antena to receiver device. Higher attenuation of longer cables can be easily compensated by increasing gain, while in the situations with very short cables and strong receiving signal zero or even negative gain assures not to overshoot input dynamic range of the receiver.
Amplifier can be easily adjusted to any value betwen - 9 and + 18 dB in the step of 1 dB.
Excellent RF parameters:
What is unique about SHARKIE is its excellent RF parameters.
Voltage Standing Wave Ratio of less than 1.2 ensures great signal power reception. Very high Third-order Intercept Point IP3 >34 dBm providing great linearity and finally industry leading ultra low noise amplifier IC with noise figure 0.75 dB.
High efficient input filters for removing unwanted RF spectrum
Sharkie high efficient input filters help to prevent receivers intermodulation with other sources in band outside of the main working range of wireless systems like walkie talkies, FM radios, wireless focus systems, WiFi and bluetooth devices, mobile phones, etc.
Performace of wireless system will be better with less dropouts.
Plug and work:
Preset value of onboard amplifier gain is displayed on Inbuilt seven segment LED display upon power on and if required it keeps displaying for permanent possible readouts.
Display has furthermore automatic brightness setting feature, which adjusts its brightness according to actual ambient light condition avoiding unacceptable situations of everywhere shining display in dark places or unreadable gain value on direct sun light.
This automatic brightness feature can be disabled by setting of fixed brightness value or the display can be completely turned off while amplifier keeps working. In this mode any button press will temporally power on the display for possibility of changing the settings or just for preset gain readout.
Top build quality:
Lightenned antenna structure is made of glass-reinforced epoxy laminate, which also covers all possibly fragile elements and ensures great durability in everyday use. Amplifier is made of CNC milled aluminium alloy and is sealed for great water resistant performance.
Antenna can be powered externally through coaxial cable from power source of 5 - 20 V DC. Professional hardware design with best in class integrated circuits results in extremely low power consumption which will be a big plus for your shooting rig performance.
