Betso Sharkie Active Sharkfin AntennaThe Betso Sharkie is a compact, wideband UHF active receiver antenna with Log Periodic Dipole Array (LPDA) structure and cardioid directivity. Main FeaturesUltra low noise onboard amplifier with adjustable gain from - 9 dB to + 18 dB. The amplifier can make up for the signal loss inherent in long RF cables. And if you're lucky enough to be getting very strong RF signal level then you can set zero or even negative gain to avoid over loading the input stages of your receiver. Excellent Standing Wave Ratio of less than 1.2 ensures great reception. Very high Third-order Intercept Point IP3 >34 dBm High efficiency input filters Seven segment LED display with automatic brightness adjustment. The brightness setting can be over ridden or the display can be switched off.
