AERIAL MOUNT ANTENNAS
Upgrade to the latest antenna technology and 
get maximum reception of the new digital TV signals. 
The sleek, aerodynamic JACK® antenna is fixed at 
11-1/4” high eliminating the need to crank up or 
down and is always ready for travel. An amplified, 
ultra high gain antenna provides the best digital TV 
reception available for your RV with superior reception
of both VHF and UHF signals and a much broader recep-
tion range. The built-in SureLock® Digital TV Signal 
Finder let’s you pinpoint the local TV towers before scan-
ning for channels for simple, fool-proof antenna pointing. 
Full 360° rotation allows for precise antenna pointing with no “dead 
spot” commonly found with other antenna mounts. An LED light on the 
head confirms power to the built-in amplifier via the supplied wall mount 
power injector switch. At just 11.25”H x 16”W x 12.5”L, the JACK® is 
up to 70% smaller than other antennas and provides superior reception 
of the new digital TV signals. Available in black or white.

REPLACEMENT HEAD 
FOR SENSAR
®
Sensar® is a registered trademark of Winegard® Company. Jack® is

by Winegard® Company. 
Replace your old Sensar® antenna with the JACK® replacement head 
for better digital TV reception. Includes custom bracket for simple 
retrofit to your current antenna mast using the existing mounting pins. 
Broader reception range helps to receive signals 
found in the “dead spot” or 35° of rotation not 
reached by the existing mount. The amplified 
antenna can be powered by your existing antenna 
power supply or used with the included power 
injector. A universal mounting bracket is also 
included for installation on a pole or railing
for residential use. At just 2.25”H x 16”W x 12.5”D, the JACK® 
replacement head is 70% smaller with improved wind resistance 
and weighs 25% less than the existing antenna head.
