Hi:
I've used an L band amplifier and a passive GPS receive antenna as the transmitting antenna to make a GPS repeater. It
was feed from an outside GPS antenna.
This allowed having a number of hand held GPS receivers sitting side by side
working inside.
Have Fun,

David,
One of these two photos is correct (odd isn't it)...

Maybe these break the tie:

] Antenna question about RHCP/LHCP I'm sure a time-nutcan
answer
This is not exactly a time related question, but I'm sure the subject must
be of interest to time-nuts using GPS.
If one transmits from an antenna such as a helical one, RHCP, can the same
antenna be used for reception, or does
Well, they could be consistent.
Most of those photos show only two sizes of helix-type antennas. The
larger diameter (probably lower frequency) are quadrifilar helix designs,
and they are uniformly left hand thread helixes. (I assume that everyone
agrees on what a left-hand thread looks like,

How about the collars at the base of them?

Slightly off-topic, the first time I was aware of polarisation error was
during the very first trans-Atlantic TV tests. On the first night,
signals were fine in France (who had a copy of the US antenna), but poor
in the UK who had designed and built their own antenna). UK changed
