Need tips prevent lnbf from lightning strikes

[intrepid]

Greetings, I have just purchased a new BSC 621-2 to put on my old bud. I haven't used it in about 10 years because my lnb kept getting fried when a thunderstorm came up. Could you give me any tips on how to prevent this from happening again. I would really love to get it up and running again. Any help would be appreciated. I have surge protection and a ground at the dish, but this hasn't helped in the past. Thanks again.

If his lnb is getting fried, how is an inline protector going to do any good to stop that after it hits the lnb?

If installed near the LNB it should short to ground instead of thru the lnb the voltage induced on the center conductor due to grounding problems. The tech-notes provide the real info. I don't think the LNB is taking a direct hit but maybe getting zapped due to rise in ground potential. A lack of common bonding (thick copper wire or strap) between the antenna ground and house gound is a common cause.

The polyphaser stuff works fairly good from what I can tell, I know of an FM radio station that had a near by lightening hit last year and thought the LNB or the receiver may have took a hit but come to find out, the polyphaser took the blunt and was dead from the strike but the LNBF and receiver was ok! (good because the recv is like 3000$ to replace and the LNBF cost like 300$)

Ofcourse with lightening, millage will very and no one can predict what it will ultimately do.
