Subject: Re: LF: GPS ANT
I've made both quad helix and crossed dipole GPS
antenna in the past - the details are on the web somewhere if you search
- but its hardly worth it now - they are so cheap and available
I have also made one in the past and it worked, but I thought someone
might have something special using the latest technology. One store quoted a
£100 for one. Mine was made from bits out of junk and cost nothing.
I do not mind paying something reasonable but two persons have promised
me free samples.
Does anyone have a
good active antenna design for a GPS rx.
You certainly can't get much more LF than that:-)
Joking apart, I've never even considered making one.
You can buy them new online for around £15, standard 5 volt supply via
the coax, and I would have thought it could end up costing more than that to
make your own in small quantities.
