- PRA-420
is an Active Antenna Power Supply, low noise MMIC
TV amplifier, and a ferrite splitter combined and designed to
supply a
small Marine TV Distribution System with 8-12 Radio and TV Outlets, or
a remote front end.
- Amplification is continuably adjustable from + 10 dB to +30dB via onboard attenuators.
- The hinged cast metal EMI
shielded case is
gasket sealed and highly
water resistant.
- External CATV type "F" connectors are
provided for the
external antenna input and 2 branch line outputs as well as for an
external
signal source such as
CATV or a VCR. An "O" ring cable gland is provided for the primary power cable.
- All PRA-4xx series will operate
from 12 or 24VDC
or is strapable for 110-220 VAC, and they can all be configured to
supply power to two antennas.
- PRA-422 is identical with the addition of a separate AM Radio amplifier with attenuator. Both devices will power two active antennas such as the PR-430 and PR431 or PR-432. when configured to do so.
- A TILT coax loss compensation circuit is available for PRA-422T.
- PRA-430, PRA-431 and PRA-432
are for AM, FM, and AM-FM respectively and will work with PR-430 series
radio antennas or the older VPA-30 antenna.
- Variable atenuators are privided for each radio band. This antenna is in common land based use for use with metal buildings where conventional antennas will not perform and on board ship for cabin/crew distribution..
- PRA-420 NSN : 5820-01-560-4184 cage
code OGMC3
- A special version is made for US Navy PRA420T16LPD17 NSN 6130-01-530-6190 cage code 0GMC3 and used on DDG, JHSV, LPD and LCS projects.
