Another way is to run each line down the center element of two lengths of RG58 (or whatever's convenient). If I run two pieces of RG-58 in parallel, I get 25 ohms. So would that mean... If I run 2 pieces of RG-58 in series, I get 100 ohms??? I wonder!!! -- KD8KC OK, here are the two cases, the first one mentioned ----------------------------- o-*-----| RG58 |----*--o | --*----------------------------*- | | / \ | 25 | | ------------------------------ | | ohms \-|--| RG58 |-|--/ o----*--*----------------------------*-*-----o And the second, where the shields are soldered together on each end: - -------------------------------- 0------| RG58 |-----0 *----------------------------------* | | 100 | | ohms *----------------------------------* O------| RG58 |-----O - -------------------------------- [ARRL Antenna Book (16th Ed.), p. 24-21] And note that *i* didn't use the term 'in parallel' here. I don't know what you would call which. Of course, two lengths of RG59 gives about 150 ohms, as would two lengths of TV twinlead in parallel might (but i'd be real concerned about proximity effects in that case). -- KD6PAG (Networking Old-Timer, "RF newbie") ---- Via the amsat-bb mailing list at AMSAT.ORG courtesy of AMSAT-NA.
