Yes, I have a National Survey Bolt mark just down the road from me. -------------------- I'm not sure that completely answers the question. Even if we assume that the position of the bolt mark is known to an accuracy of an inch or so, have you measured your antenna position in relation to that with sufficient precision in distance and bearing so as to transfer that accuracy to the antenna location? regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
