    Impedance bump from coax sheld grounding?

    Brian, thanks. My website reference to MOV-life of 10 surges does accurate apply to all UL approved power-strip surge suppressors, of the garden variety found in most homes in America. I "accidentally" applied that fact to large MOV's that are very properly installed at installations from...

    Impedance bump from coax sheld grounding?

    VE1BLL, I spoke with the USCG Auxiliary Air Commander for the District this afternoon, and they are using off the shelf marine vhf radios mounted aft of the cockpit. They will discuss your question about DSC capability at a meeting later this week at USCG AirSta Elizabeth City. The C-130's and...

    Impedance bump from coax sheld grounding?

    Thanks for the reminder about impedance-bump, re: not materially affecting MF/HF work for short lambda insertions. I am of the opinion that additional shield grounding will not affect the balanced operations at resonant frequencies of the dipole antennas. But at higher frequencies where antenna...

    Burden Rate

    Burden rate for a machine or a division would use all the direct labor costs excluding G&A for that machine or Division. While engineers probably taught accountants how and why life-cycle and other total cost principles were needed..in today's industry there is no way "an engineer" can be...

    Impedance bump from coax sheld grounding?

    After installation of multi-mode coax lightning arrestors, I have referenced several techincal papers that call for shield grounding at building entrance (done) and also at the bottom of the vertical drop and top of tower. My question relates to HF transmitting to a horizontal wire dipole...
