Page 3: Warnings
WARNINGS FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN A SERIOUS ACCIDENT. • NEVER CLIMB OR WORK ON THE ANTENNA WHILE RF POWER IS BEING FED TO IT. WHEN WORKING ON THE ANTENNA ARRANGEMENTS SHOULD BE MADE WHICH WILL GUARANTEE THAT RF POWER WILL NOT BE APPLIED WITHOUT SPECIFIC INSTRUCTIONS FROM PERSONNEL ON THE TOWER. - Page 4 Many issues need to be considered during the planning, purchase and installation of a new Dielectric TFU UHF television antenna. The purpose of this book is to assist the station with the final phase of their project; the delivery, inspection, assembly, and installation of their antenna.

Page 5: Description
DESCRIPTION General Dielectric side mounted UHF Pylon Television Antennas (TFU) consist of slotted aluminum pipes with diameters and wall thickness of proper size to provide the specified electrical and mechanical requirements. These antennas are supplied in one of three basic forms. Figure 1 (a) shows a typical waveguide input antenna installation, Figure 1 (b) a typical coax input antenna and Figure 1 (c) shows an antenna side mounted on a pole for tower top installation. -
Page 6: Equipment For Installation
Delivery and Storage The side mounted TFU antennas are typically shipped on shipping deck saddles or blocks on a flat bed trailer. In Figure 2 a typical pole mounted antenna is shown ready for delivery. The antenna and trestles are strapped to the bed of the trailer while spare parts and other accessories are packed in cartons and shipped with the antenna. -
Page 7: Inspection
Parts removed to facilitate the shipping are located in the cartons and can be installed prior to or after installation. If any parts for which spares are not supplied are found to be damaged or missing advise Dielectric. ANTENNA UNLOADING AND ASSEMBLY Appropriate equipment should be used to safely unload and handle the antenna, components and cartons. -

Page 13: Lightning Protector Assembly And Mounting. (If A Support Pole Is Used)
Pole steps may have been removed for shipping purposes. There are two common sizes of galvanized steel pole steps used by Dielectric. These are 1-1/8 and 5/8 inch. In rare cases when extra length is required a 1-3/8 in size may be used. The pole steps thread directly into the pole and are locked into place with a jam nut. -
Page 14: Final Pre-Installation Procedures
On dual lighting systems two cables can be supplied. Exact requirements of the lighting system must be communicated to Dielectric at the time of order to assure that the support pole is supplied with the necessary components. Some systems require a single cable, while others require two. -
Page 15: Antenna Installation
All radomes should be inspected for cracks incurred from tower site handling and alignment. Make sure all mounting hardware is installed and tight on any radome panels removed for shipping. In the event that there is a problem with any of the above please contact Dielectric. ANTENNA INSTALLATION General •... -
Page 16: Lifting Antenna
Lifting Antenna Rig the antenna as shown in Figure 3. Lift the antenna, maintaining a horizontal attitude. Slowly relax the line that supports the bottom half from the chain puller/hoist. This line will support the antenna until it has reached an angle of approximately 60 degrees (See Figure 7). After the load has been relaxed from the top and bottom support line, the antenna is ready to be raised to it’s mounting spot on the tower. -

Side Mounted Antenna - Dielectric Supplied Mounts Refer to the assembly or installation drawing for details regarding placement of components. Dielectric recommends organizing the components from the shipping container(s) in a manner to match the drawing. • Follow General Instructions for antenna handling. -
Page 18: Final Test
FINAL TEST Dielectric personnel or a Dielectric representative will test the antenna and the antenna system. The representative will verify that the system meets specifications and review this data with the customer. Power should not be applied to the system until after review of the test data and acceptance by Dielectric and the customer. -
