Tks for the correction, Jim, and for letting me off the grammatical and
purist "hook" with your comment about VW beetles and buses {;?)
My mentor was a radio ham and a USN Chief Radioman during my first four
years as a navy radioman before becoming a mud-diving fool for my second +
years' hitch. He was a sticker for the jargon and a bit of a purist - and
always insisted that my reports and recommendations for multiple antenna
usage be spelled with the "ae." Guess I've never gotten over that ...
The Morse Code (former Tech +) requirement no longer exists for amateur
radio licensees. So, if you obtained your "Tech" license, and want to do
just a little reading (if you don't already know your electronics and rf
radiation "stuff"), you can sit for and pass the "General" license and get
on the air. Just contact a local radio club (the ARRL and/or QST magazine
lists the clubs) and ask when their next class or next exam date is
scheduled and pass the 30 question exam.

Everytime I see someone using the word for antennae relating to electronic
signals, I think of an insect with a ham radio strapped on its back ;-) So
in the humorous spirit of "Frydaye", here's my take on this....
Terminolgy is where its at these days volks.....On of the first things I
learned in both high school biology and electronics is the correct
terminology of antenna, antennas or antennae (the electronics teacher had an
obession about drilling these differences home to us hapless students who
didn't know the difference between a Yagi or a Ground Plane antenna).
Antennae is the plural for antenna(s) on certain members of the animal
kingdom, to wit: *Antennae* (singular *antenna*) are paired
appendages<http://en.wikipedia.org/wiki/Appendage>connected to the
front-most segments <http://en.wikipedia.org/wiki/Morphogenesis> of
arthropods<http://en.wikipedia.org/wiki/Arthropod>. In crustaceans
<http://en.wikipedia.org/wiki/Crustacean>, they are
biramous<http://en.wikipedia.org/wiki/Biramous>and present on the first two
segments of the head, with the smaller pair known as *antennules*. All other
arthropod groups, except
chelicerates<http://en.wikipedia.org/wiki/Chelicerata>and proturans
<http://en.wikipedia.org/wiki/Protura> which have none, have a single,
uniramous <http://en.wikipedia.org/wiki/Uniramous> pair of
antennae.Antennae's also are used to send signals to communicate. 20% of all
bugs have antennaes. Antennae are jointed, at least at the base, and
generally extend forward from the head. They are sensory
organs<http://en.wikipedia.org/wiki/Sensory_system>, although the exact
nature of what they sense and how they sense it is not the same in all
groups, nor always clear. Functions may variously include sensing touch
<http://en.wikipedia.org/wiki/Tactition>, air motion, heat, vibration
(sound), and especially
olfaction<http://en.wikipedia.org/wiki/Olfaction>(smell) or gustation
<http://en.wikipedia.org/wiki/Gustation> (taste). (From Wikipedia -
underlines are theirs, not mine)
Antennas are the plural form for antenna, that is those that are used for
transmitting and/or receiving selected electronic signals of the radio,
television, etc., to wit: An *antenna* is a
transducer<http://en.wikipedia.org/wiki/Transducer>designed to transmit
<http://en.wikipedia.org/wiki/Transmitter> or
receive<http://en.wikipedia.org/wiki/Receive> radio waves
<http://en.wikipedia.org/wiki/Radio_waves> which are a class of
electromagnetic waves <http://en.wikipedia.org/wiki/Electromagnetic_wave>.
In other words, antennas convert radio frequency electrical currents into
electromagnetic waves and vice versa. Antennas are used in systems such as
radio<http://en.wikipedia.org/wiki/Radio>and television
<http://en.wikipedia.org/wiki/Television> broadcasting, point-to-point radio
communication, wireless LAN<http://en.wikipedia.org/wiki/Wireless_LAN>,
radar <http://en.wikipedia.org/wiki/Radar>, and space
exploration<http://en.wikipedia.org/wiki/Space_exploration>. Antennas
usually work in air or outer space, but can also be operated under water or
even through soil and rock at certain frequencies for short distances.
(again, from Wikipedia - underlines are theirs, not mine)
Of course, on vehicles that looked more like insects (like the Beetle or
Bus), maybe antennae does apply.......;-)
That Bus does have one helluva an array tho...

If that guy's antennae can be used to receive normal analog TV signals, then
he will be able to get DTV signals, too.
But picking up DTV in the boonies will probably be harder. Unlike analog TV
where the receiver can tolerate a pretty weak signal but still give you a
picture (though with noise and multipath and sync problems), DTV is
all-or-nothing. Once the signal gets too weak or filled with too much
multipath, the TV will just give you a blank screen.

Mike,
So the poor guy in the photo from the link I sent, won't be able to get
digital with his little antenna either.

Where we live we have good TV signals. But we never get good programs. I
asked the man at the electronics store if the new HDTVs made the programs
any better and he said he didn't think so.
Keep in mind that after Feb 17, 2009, all television broadcasters will shut
off their analog signals and broadcast only in digital. New antennae, new
tuners, will be needed. See
