| Subject: | what is the truth about gps antennas? |
I'm interested in hearing from an engineer who might know about what really goes
on with my stratus esg gps antenna. they say to use RG400 cable, 10' minimum,
and never paint the antenna. they also told me the strength ratings should run
in the 30's. I have 3' of RG400 with a mechanical 90 elbow, I spray painted
the antenna flat black and mounted it on the glareshield of my RV. my readings
are all in the 40's. they told me this shows an overdriven condition.
so why use low impedance cable then need 10'? my iFly740 and Lowrance 1000 gps's
have antennas with much smaller cables. the iFly shows WAAS grade accuracy,
using an antenna 1/4 the size of the stratus RAMI antenna.
when does being overdriven prove to be a problem? is this a situation where I could
add more mechanical connectors to increase impedance rather than more cable
length?
I get the feeling things get written and then forever repeated, such as never paint
an antenna, without asking any questions. could I use a different antenna
than the RAMI brand? should I not worry about any of this and just go fly?
