SPX shows new antenna series for low-power TV9 September 2011
The new DLP-V and TLP-BB series of antennas from SPX Communication Technology brand Dielectric have been designed specifically for low-power TV applications including transmission systems (DTS), gap fillers, mobile media broadcasting and translators, writes Michael Burns.
A supplement to the TLP series of antennas, the low-power, single-channel slotted DLP-V series features 30 percent vertical polarisation 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 polarisation, the non-pressurised DLP-V and pressurised TLP-BB are standalone 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.
