Hi Folks I'm not so hot on RF stuff (actually not so hot on anything above 50/60Hz - only studied power stuff) so thought I should ask:
I have a few GPS antennae here, all with 5m (15ft-ish) cables on them. For me, that won't get the antenna anywhere near the highest ridgeline of the house. (Australian "Federation Style" house - lots of weird bits of roof all over the place.) So, I need to extend the cable. 1) Can I actually extend the cables, or is 5m as far as I can go - all these are active antennae. 2) My normal way of extending a bit of coax would be to splice in an appropriate length of similar cable. To do this, I would strip the outer insulation for a couple of inches on both pieces, pulling back the braid. I would then strip enough of the central insulation so that I can solder the two cores together. I insulate this with tape or heatshrink, then solder the two braids together, wrap the whole thing with aluminium foil and use a glued heatshrink to case the whole lot. I know that this method works for 10-Base2 Ethernet and UHF Television, but have no idea if is suitable for SHF stuff like 1.5GHz... 3) How far apart do I need to space my GPS antennae, or can they be nearly touching? I suppose it would be easier if I used a distribution amp (assuming such things exist at this frequency), but that sounds expensive.
