Well... My house was made in the 70s so copper pipe is literally down 10 feet in the ground from the street to my house -- ALL COPPER ... and actually it comes up from the bottom of my basement floor - thus grounded. In addition, my electrical box is grounded using a ground ROD and the boiler's electrical ground pulls from that ground thus seems to be all well grounded... I have confirmed this with Ohm Meter.. at various points on the plumbing..
I guess I would like to know is there any downfall of grounding - especially on transmit or receive? The ground I have right now is NOT a safety ground more of an RF ground - and if so is it really a RF ground and is it helping any? I dont have any common mode current and little near field as the antenna is not all that far from my shack.
Safety grounds should happen outside which I have on my mast but NOT on the coax.. So I guess that's the other question should I ground the coax? Does THIS affect receive or transmit?
Any advice appreciated.
If your hot water pipes are grounded, it's probably purely incidental with the connection occurring at metal sink faucets. Not what you want or need. These days, it would be unusual to find metal cold water pipes that actually go into the ground. Any and all cables coming from outside the house should be connected to ground at a single point, ideally where the electrical, phone and cable TV lines come into the house. If that's impossible, at least run a heavy copper wire connection from a single point radio cable ground panel to the electrical panel ground rod. There's tons of info on how to do station lightning protection grounding and that's what you want to search for. It's been covered many times here on the Elmer's forum - try the search here. Also, check out the Polyphaser website for more info on the subject. It's only necessary if you want to protect yourself, your gear and your home from lightning damage.
