Jeff, The question is way off base. No one said one cannot carry DC or any other signal on coax. The question was what was the impedance of a coax at given frequencies.
At DC I can guarantee you RG59 is not 75 Ohms unless you got enough to get enough R and this is totally another discussion. I would think you would agree one will not see RG59 being 75 Ohm at DC. The same can be said at 1 Hz or 2 Hz or 5 Hz...etc. There is a point at which it starts to propergate and does look like 75 Ohms. I think you might understand this. 73, ron, n9ee/r >From: Jeff DePolo <[EMAIL PROTECTED]> >Date: 2007/09/01 Sat PM 01:18:35 CDT >To: [email protected] >Subject: RE: RE: RE: RE: RE: Re: Re: RE: [Repeater-Builder] Re: Duplexers > >> I don't know where the confusion is...all coax and feedline >> has a upper and lower freq limit.
