This is for installers (both E* and subs alike). I DO NOT want to start a bashing thread. I would just like to know the OPINIONS and EXPERIENCE of what you do and what you have seen with installations as it relates to system grounding.

In regards to system grounding, I have some questions...

1. How likely is it that a dish will be hit by an electrical surge, and thus transfer that energy to the receiver and render it inoperable?

2. The LNB is plastic, as is the Y or W adapter, so if the LNB were hit, wouldn't be where the hit would stop? I know that a lightening bolt, if it hit the dish / LNB directly, would probably blow it off the roof, side of the house, etc., and it would have to be replaced, and thus, would more than likely be the least of your worries.

I'm thinking that a grounding block is not going to arrest such a violent source of electrical energy.

3. If the dish were hit, and the LNB is plastic, how would the energy be transfered to the electronics?

4. I know that it is a requirement for a system to be grounded, but...

a. How many installers actually do what they are supposed to do and ground EACH AND EVERY SYSTEM, especially since most subs probably are paying for all of their own supplies and equipment?, and may not get reimbursed by your retailer.

b. What percentage of systems do you ground?

c. What is your criteria / rationale for NOT grounding a system if you don't?

5. Isn't it most likely for a system to be hit with a surge through the phone line, rather than the coax? or the power cord (being that it has it's own grounding terminal)?

I've read about static buildup, and this is more likely the reason why the system is to be grounded, rather than lightening as the rationale. Is the static buildup really that intense?

6. What percentage of receivers, that you've had to replace, if any, would you say are a result of 'failure to ground'?

7. If you are a sub, what does your retailer say about this issue? Are you penalized in any way for 'failure to ground'?

What other regarding this subject can you shed light on? Is it REALLY that CRITICAL?

It is not always that the dish is the highest point of the structure. Sometimes they are in the ground on a pole, the side of the house, low on the roof, etc.

PLEASE, don't bash me or each other. I just have some questions and would like to know what you think / do, etc.

Thanks.
