"Jay" jgibson1 AT COM CAST . NOT wrote in message
... [snip] However, if you intend to cut the cable into two pieces and then splice these two pieces together, you'll have big problems. At these frequencies losses will be huge and the impedance change large enough to (possibly) damage your unit. [snip] I too, am a long time amateur radio operator, and know quite a bit about electronics/radio. What I don't see, is how signal loss, and/or impedance changes, will "damage" the unit. GPSRs are receivers, and receivers only (outside the non-incidental spurious emissions from normal operation), the worst that could happen, would be a loss in RX signal strength. I cant see causing any damage to a GPSR by changing the antennas impendence, other that poor(er) performance. -- -Netsock "It's just about going fast...that's all..." http://home.insight.rr.com/cgreen/ |

Sorry, i was stuck in TX mode lol. You are right. For a receive only
unit a paper clip stuck in the back won't hurt it. Heck, a paperclip would just about be a 1/4 wave dipole at those frequencies! Jay (Standing corrected) "Netsock" wrote in message ...
