thanks to , groundurmast and teleview for their advice on purchasing a rca ant-752 antenna . I just received it and assembly is very easy but the base does not look like it will connect to the satellite mast [ direct tv ] , could someone suggest a way of doing this ? also what is the proper way to ground the antenna for static discharge and lightening ? I have a grounding rod just below the sat dish which is mounted on the roof .
thank you , naturl

The following is a Teleview recommendation for broadcast Tv reception.
Go to Home Depot and etc. , find a smaller pipe that fits inside the satellite tv dish pipe.

thank you teleview , I think I figured out the proper grounding but was hoping there was a simple way to mount antenna without removing the satellite dish
[ no access to pipe without removal of dish ] . since direct tv didn't want their dish back I guess I will remove it myself .
thanks , naturl

My stock answer is, Grounding the mast and coax shield are prudent and relatively inexpensive steps that limit the buildup of static-electricity which can damage the tuner. When done correctly, grounding can also reduce the risk caused by a nearby lighting strike.

Grounding in a basic system is a two step process:
1) Connect a #10 gauge copper wire to the antenna mast. A bronze ground clamp such as the Halex #36020 is well suited for this application. Run the wire directly to the electrical service ground. Avoid sharp bends in the wire. (If the ground wire between the service panel and ground rod is accessible, an Intersystem Bonding Termination devise (http://www.homedepot.com/Electrical-Breakers-Distribution-Load-Centers-Accessories-Other/ERITECH/h_d1/R-202194170/h_d2/ProductDisplay?catalogId=10053&langId=-1&productId=202194170&storeId=10051#.UB9y8qCOyzo) can be placed onto the ground wire without cutting or disconnecting it. This provides a means to connect the #10 mast ground wire to the existing ground wire close to the ground rod outside the building. If possible, avoid running the new ground wire inside the building, energy from static or electrical storms is best directed to ground before it has any path into the building. The mast ground wire can be bare or insulated, your choice.)
2) Run the coax from the antenna to a location close to the electrical service ground. Install a ground block (http://www.amazon.com/gp/product/B001I5610E/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B000BPEZKK&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1C90NDN0N2CS08266D7Q) and with another peice of #10 wire, connect it to the electrical service ground at the same point you connected the mast ground.
I don't recommend short-cuts such as driving a new ground rod that is not connected to the existing electrical service ground. An isolated ground rod often has a high resistance that provides very limited ground connection. The goal is to connect to the same ground system that protects the rest of the home.
Surge protectors located inside outlet strips at the TV, computer or similar devises are worth consideration. A surge protector with a high joule rating is able to absorb more fault energy than a unit with a lower joule rating. Some surge protection units include phone jacks and F-connectors to enable protection of a phone line, coax cable and the power cable(s). However, in the case of an outdoor mounted antenna, this type of protection should not be considered a 'first-line of defense'.

thank you GroundurMast for the information . your instructions are easy to follow and I think the installation can be completed with no problem .
again thanks , naturl
