This Plate has a collar with a Set Screw that securely holds the Telescopic Mast Tube in place and can be in turn, cemented into the concrete Pad via the Pin provided. The word "Ground" as used in the description can be a bit of a misnomer; it does not provide a "Earth Ground" in and of itself, but rather is a junction component that rests on the ground or pad and should be Bonded to with a proper Earth Ground composed of a 5/8 inch by 8 foot Copper Clad Ground Rod as a minimum. Consult your Local Building Code and NEC for guidance to Properly Grounding your HD TV, WI-FI, Wireless Internet, Business Band, CB or Amateur Radio Antenna Installation.

Telescopic Antenna Mast Mounts

It is Important to choose a Mount and Mounting Location with a Picture of the Finished Installation in Mind. Be Sure to First select a location that lends itself to applying a Load without Compromising the Integrity of the Material you affix to. Most Decorative Finishes most often do not have the Strength to Hold a Weight or Pressure without fail. Further, Think about what's underneath the exterior. Is it stronger, or will it yield to Pressure over time also? Weather Proof the Installation to Maintain the Integrity of your Home. Next consider the Location over a Lifetime of Adjustments, does it lend itself to modifications in Height or Direction? Larger Antennas increase the surface area presented to air movement, Hence, Wind-load does increase. As the length of the mast increases from Its last attached point on the structure, the torque applied in cantilever also increases with Weight and Wind-Load, requiring a more substantive attachment and Load-Bearing material. Keep the Distance Minimal from the Antenna to the TV's and Equipment you feed, as to minimize loss and the need for Amplification.
