SPX Introduces Dielectric Low-Power Antennas
RAYMOND, MAINE: SPX Communication Technology (formerly Dielectric)
today introduced its new Dielectric DLP-V and TLP-BB series of low-power antennas
designed specifically to provide broadcasters with economical choices for low-power
TV applications. These include distributed transmission systems, gap fillers, mobile
media broadcasting, and translators.
A supplement to the TLP series of antennas, the low-power, single-channel slotted
DLP-V series features 30 percent vertical polarization to increase signal penetration
for gap-filling scenarios and a more reliable signal. Offering an eight-bay, single-module
design, the antenna provides 1.7 kW input power and beam tilt of 1.5 degrees.
The TLP-BB broadband antenna can be used to multiplex numerous low-power stations
due to its broadband width of 60 MHz (up to 10 channels wide) with a VSWR of less
than 1.15. The antenna offers a 12-bay, double-module design with two six-bay slotted
antenna sections fed with a common power divider, cables, and line hangers for multiple-channel
operations. The TLP-BB offers 7 kW power input and beam tilt of 2 degrees.
Offering either horizontal or elliptical polarization, the non-pressurized DLP-V
and pressurized TLP-BB are stand-alone products that feature simple mechanical designs
for ease of installation. The antenna structures can withstand wind speeds of 125
mph, and they feature low-profile slot covers for environmental protection.
Standard mounting hardware is provided in pipe sizes from 1-1/4-inches to 4-1/2-inches
and angle leg size from 1-1/2-inches to 3-inches. The DLP-V offers a single standard
7/8-inch EIA input, and the TLP-BB features a standard 3-1/8-inch EIA input. The
DLP-V is available with standard directional Azimuth pattern options while the TLP-BB
is available in B or M Azimuth patterns.
