A> Alan A> WA4SCA Rule of thumb for GPS antenna location - more unobstructed sky view is better. Less reflective objects around antenna is better. Sometimes nearby transmiting antennas may represent problem, if there is oxidized compression joints that may act as "frequency multiplier" (non-linearity). Height is not so critical, unobstructed sky view is much more important... -- Best regards, Yuri UA3ATQ/KI7XJ mailto:[EMAIL PROTECTED] _______________________________________________ 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.
