Page 3: Warnings
Warnings: The purchaser is responsible for determining if the support structure, pole, tower or mast will safely handle the antenna system. For reliable, moisture free operation, maintain 5 psig of dry air or dry nitrogen to the antenna system at all times. Failure to keep the transmission line and antenna pressurized with dry air or nitrogen may allow moisture into the system can cause arcing and physical destruction of the coaxial system. -
Page 4: Uncrating
Prior to opening any crate(s) or removing strapping from skids, inspect for shipping damage. Notify the carrier immediately of any observed damage to the crate. Note: TLP-8: The antenna single section is shipped under pressure and should remain so until installation. -
Page 5: Assembly/Installation
Apply a light coat of the provided non-melting silicon dielectric lubricant (Dow Corning no. 4 compound) to the O-rings at time of assembly. The lubricant will aid in holding the O-ring in the seal groove. Always be sure the lubricant is applied very lightly. -
Page 6: Tlp-8 Assembly And Orientation
♦ Antenna sections are not the same, do not interchange the sections from their designated order. A. TLP-8 Assembly and Orientation 1. Assemble mounts. (Reference Universal Mount drawing in the information folder) 2. Locate and install antenna to supporting structure per Installation Drawing. -
Page 7: Leak Testing
4. Repeat for the remaining section(s). 5. Clamp the saddle mount to the power divider and mount on the tower central to the antenna array. Release the pressure and remove the gas cap from the section and the corresponding cap on the power divider. Then connect the feed line matched marked for that section. -
Page 8: Purging
PC=corrected final pressure, psig PR=final pressure as read, psig T1=beginning temperature, degrees F T2=final temperature, degrees F Note: A rule of thumb is that the final pressure should not be less than half the initial pressure after twenty-four hours. 6. If the system looses pressure at an unacceptably high rate, re-pressurize. Leave the gas/air supply on and find the leak(s) using a “leak detector”... -
Page 9: Pressurized System
Before powering the system perform the following inspection; Antenna system has been installed per the installation drawing(s). The system is gas tight and purged. If an antenna checkout was ordered, a Dielectric Representative will give approval to apply power. Operation To start up apply transmitter signal. - Page 10 Check transmission lines for breaks, loose or missing hardware, chafing and so forth. The transmission line itself should be visually checked for signs of changed alignment, undue stressing and loose coupling clamps and hardware. Inspect the antenna mounting hardware for tightness. Observe the dry nitrogen gas/dehydrated-compressor air usage as an indication for system leaks.
