BEKO HLV-770 70 cm RF Power Amplifier
“Designed for Weak Signal, Tropo Scatter, Meteor Scatter, Digital, & Contest Operation!”
The BEKO HLV-770 employs advanced German-engineered, solid-state technology to deliver instant on, no compromise performance.
The HLV-770 is the ideal amplifier for contest, portable, EME & home station operation due to its small foot print and light weight. BEKO amplifiers are “the best of the best” VHF UHF & SHF high-power linear amplifiers available worldwide!
HLV-770 Features:
* Instant on, no warmup is needed. Don’t miss the opening!
* No tuning required
* WSJT / FT8, Digital Mode at rated output
* New, super-fast, accidental-overdrive / spike protection up to 150W
* Built-in IMD indication
* Extremely High efficiency
* VSWR, overdrive and temperature protection
An integrated sequenced voltage to control external mast-mounted preamplifiers is provided. A built in Bias-T allows the preamp voltage to be injected onto the coaxial cable. For those preamplifiers that can’t be powered via the coax and require a separate DC cable, the sequenced voltage is available via a back panel connection. As with all BEKO Elektronik amplifiers, a front panel switch allows the user to select external preamp on/off function thus allowing the preamplifier to be switched in-line or off-line. See us for suitable mast-mounted preamplifiers. The HLV-770 provides a direct connection to the HPP-432 mast-mounted preamplifier. Note: Antenna systems that have a DC short at the feedpoint require an external DC block at the antenna or the separate DC cable from the amplifier to power the preamplifier.
