You can get inexpensive conductive foam from Amazon.

Hello, Time-Nutters--
I saw a rather expensive GPS antenna made by one of the
big-name GPS survey equipment mfgrs that was mounted
on top of a 12 or 15 inch diameter disc about 3/4 inch thick.

Mea culpa. However, I did propose the option of choosing flat rate
boxes in lieu of the envelopes, and no one replied with such a request.
This was actually Bob Camp's idea, and he was the only one who
specifically asked for this packing method. It costs substantially more,
but apparently is
These turned out to be made by Fairchild.
If you expressed a desire to purchase one or more of these chips, I'll
be contacting you soon with total cost. If you have a preference for
packaging, please send me a note. Some evidently prefer the small flat
rate box, although I'd planned to ship
God willing and the creek don't rise, I should receive 50 of them within a few
days, so if you're a Stateside Timenut, this might be helpful to you. If
interested, please contact me off list with your zip code, and I'll provide a
cost estimate. Final confirmation after I've actually got them
I'm crossing my fingers that my order doesn't get revised by an
unscrupulous or overly-optimistic vendor, but assuming it gets filled,
as of 20:56PDT I have requests for all of the 50 chips I'm hoping to be
able to provide. If you requested one or two, I put you down for two.
Hopefully
Stanley,
If it's not too late, could I order 2 boards, please?
Thanks!

Does someone know which commercial antennas are 3D designs? Sounds like
the $200 AeroAntenna version mentioned previously might be a 3d design,
although it's a little tough to guess by simply looking at the enclosure
and a single drawing. An evaluation of some 3D antennas:
I believe he's referring to the Fairchild A-10A bubble sextant,
originally produced in the 1940s. I used a periscopic sextant in the
KC-135, an improvement over the hand-held, or dome-mounted bubble
sextant, but I never used any sextant in the Fairchild Republic A-10A

I picked up a couple of prewired cables for the Palisade from tiger-

They had both short (~2 or 3m) and much longer cables in stock. Prices
weren't bad, either, as I recall.

The diode
Bruce,
Thanks for the ideas. The HSMS-2822 looks like it could serve in the
detector role, while a pair of HSMP-3822's might work for clamping--low
capacitance, matched pair in series, and in stock at Mouser. The 3822 is
actually a pair of PIN switch diodes, but couldn't it function as a clamper?
Having seen it discussed, I was wondering whether anyone has actually added
the Schottky diodes and prescaler chip to a 5334B to provide a C-channel
input. The matched Schottky quads (5082-2831) are no longer available, and
even the recommended replacements (5082-2303) seem scarce. Was thinking
Can anyone suggest a source for the TAPR GPS interface for the Oncore UT+?
Thanks!
