HPR.0990 Antenna incorporates
tried-and-true AM design improvements to
boost output efficiency: increased
length, diameter, coil capacity; the
addition of a capacitive top hat. Above,

KODIAK ISLAND, AK, Dec. 2021: The Pacific Spaceport Complex in
Alaska will be keeping visitors safe and informed during
launch activities through the use of a
RadioSAFE Information Radio Service
provided for the facility by Information Station
Specialists. Based around the
HPR.0990 High Efficiency Antenna System, the
RadioSAFE system is capable of more range than
conventional systems of its class, allowing the
Spaceport to push the signal across their expansive
launch pad area and beyond. A special waiver of signal
intensity is required from the FCC for the increased
coverage.
The high
efficiency antenna is becoming commonplace due
to the need for enhanced signal range on
projects and because the FCC routinely grants
permanent waivers to permit its use with 10
watts. Depending on the location and frequency,
a coverage enhancement of 2 to 4 times is
possible. The antenna can also handle hundreds
of watts of power, which makes it a prime
candidate as an auxilliary antenna for
commercial broadcasters, as well as for special
higher-power operations in the Travelers
Information Service. Example: Hudson County, NJ,
Department of Emergency Management is currently
operating with a waiver that permits temporary
operations at 100 watts. Waldo
County, ME, performed signal tests on a temporary
basis at 200 watts. The HPR.0990 antenna can be
retrofitted to certain existing Information
Radio Stations that desire greater range. The
same is true for the high efficiency
AN2X antenna, as well, which is more
appropriate for roof installations. At this
writing, licensees
with permanent waivers for enhanced Information
Radio signal
coverage include . . . |
