Hi Bob S, An HOA can be a daunting problem, but not one that cannot be solved with a little guile.
Every house I have ever seen that has modern plumbing has a few vent stacks on the roof. Would the HOA even notice if yours sprouted another one dark weekend evening? All the kit you need to add one to your roof is available at your local big box store. The usual bullet style antenna, sitting on top of a PVC vent pipe would be invisible on most houses, particularly if it were to be placed in the same vicinity as the rest. Also, GPS bullet antennas are pretty well sealed, save for the connector on the bottom. If you do a good job of sealing the connector (eg. lots of wraps of electrical tape, followed by a few of friction tape) there in no intrinsic reason you couldn't safely mount yours on top of the main plumbing vent stack. Drill a hole in the side at some convenient spot inside of the house, and snake the coax up through the vent stack, mount the antenna over the top, leaving adequate vent space. (OBTW, it isn't a vent stack until it is above the highest fixture in the house.) Although I don't have an HOA on my farm, I have my antenna mounted that way on my radon mitigation pipe. I bent up a couple of pieces of aluminum to make an open plug and put the antenna up without ever setting foot on my roof. I simply snaked the cable up and out the top of the radon pipe, and when I could reach it from a window, installed the GPS antenna, and aluminum "plug", and then pulled the antenna cable back through the pipe, causing the plug and antenna to pop into the pipe mounting the antenna. -Chuck Harris Bob Stewart wrote:
Hi Bob, Thanks for taking the time to explain the 4ns and 20ns wanders. I have just been calling them "constellation errors" without being able to explain it better than that. I've also wondered how much of the 20ns, if any, is attributable to the PRS-45A. I still don't have the antenna located in a position suitable for precision timing. The power of the HOA is not to be trifled with. That, and the sky is full of power lines and other junk around here. Bob
