Anyone know what the propagation delay temperature coefficient is for RG6U coax and how much it varies between different brands of cable?
In my efforts to improve the Tbolt's performance to make it into a better Cs substitute, test suggest that the temperature coefficient of the antenna lead-in cable's propagation delay is contributing to diurnal errors. Anyone have a idea for a SIMPLE & cheap voltage controlled delay line that can be changed by a few ns as a function of the outside air temperature? As an alternative, Mark, want to consider adding another LadyHeather feature that tweaks the Tbolt's cable delay value as a function of the outside temperature? If interested, I have a couple ideas of how to get the outside temperature to LadyHeather. ws _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
