Hi Bill, see my comments below. Not sure it's a good idea to seal the antenna in a plastic box. Definitely will vent it from the bottom! Must get hot in there. And mounting it under a big Yagi? Uda would be pleasantly surprised to see what has evolved from his first antenna!
I considered using a puck antenna and protecting it with a black plastic conical cap that is used to keep seagulls off the top of dock pilings. Air could circulate under the cap. Tested the cap in a microwave oven, stayed cool. Didn't use it, though, got a HP conical outdoor antenna instead. Why would you want to attenuate the precision of the time signal by 6 db? The caption says, "Precision Attenuator." :-) Was worried the signal would come out as a 5MHz sine wave, but it did not! :-; But, it does turn the 5 volt P to P that comes out of the Trimble into 2.5 volt P to P. It must be a Precision Broadband Amplitude Only Sine Wave Signal Attenuator Thing-E! Guess you could call it a PBAOSWSATE for short! All the best, George Bill Hawkins _______________________________________________ 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. _______________________________________________ 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.
