Now what ever happened to those
cute car-mount cell phone antennas? Guess they're in antenna heaven along
with the K40s. Sincerely,

Nope. The cell phone antenna on the vehicle roof has been replaced by
a GPS telematics antenna, GPS map antenna, wi-fi war driver antenna,
XM/Sirius DAB antenna, GPRS antenna, and possibly a mobile DTV
antenna. Aerodynamics and safety have dictated that today's vehicles
have curved roofs and air bags in the door columns, making most
permanent roof top antennas impossible. Besides, most of today's cell
phones do not include an external antenna connector or need a car kit
"docking station". Besides, modern cell phones have to handle a wide
variety of frequencies for world cellular coverage, GPS, wi-fi,
Bluegoof, mobile TV, WiMax, and whatever else can be crammed in. A
single external antenna just isn't going to work without a diplexer
and multiple connectors. At least the antennas are now all internal
or the typical smartphone will look like a porcupine antenna farm, or
if retractable, a Swiss army knife.

Incidentally, the K40 has been replaced by the Wilson 1000 and 5000 as
the mobild CB antenna of choice.

Good to 5,000 watts AM or 20,000 watts SSB. For mounting elsewhere on
the vehicle, there are antennas with oversized stainless base or
center loading coils that could probably survive a direct lightning
hit. Of course, you need two of them with a "co-phasing" harness.
