1460 - Model of a suspension equipped steerable tongue?

Yes, the Double Bow is pretty poorly matched down in the lower UHF
frequencies. It should still beat a loop, though.
The Silver Sensor is probably a better choice overall, especially
after February when most of 52-69 will go dark.

It's the famed Double-Bowtie antenna. It's too small for really good UHF
reception (should be 16 inches wide or perhaps slightly wider, it's
actually 12 inches wide), and it tends to fall over. It is, however,
one of the the best indoor UHF antennas around. It's discontinued now
but it sold for years in Radio Shack and as the Channel Master 4149,
so it wasn't exactly a commercial failure.
Summit Source apparently still has some under the Channel Master part number.
I've gone all-OTA myself, with a Channel Master 4221 (same idea, only
considerably wider and with four "whisker-style" bowties -- it's an
outdoor antenna) and a neutered Terk HDTVo for VHF.

In the days before cable I built a 7-element quad loop antenna for a
friend in the Philly area who wanted to watch NYC's Channel 9 (ESPN?)
but couldn't quite pull it in. With the antenna sitting on a pair of
sawhorses in his garage, reception was "like right next door!"
It didn't bother him that it only worked for the one channel.

Back about 1980 I was similarly impressed, so I bought one. I was
disappointed. IIRC, I found no improvement over rabbit ears or a loop
for UHF gain and multipath rejection.
I don't know if others were similarly disappointed. The classic design
uses wires like cat whiskers for the bow ties. I don't know if metal
plates are equivalent. The classic design has 10 cm between the bow
ties and the reflector. This one has only 5 cm. The classic design
uses series/parallel wiring to get 300 ohms. The indoor model looks
like 75 ohms, which could mean standing waves in the transmission line.

For all the time I spent studying all that stuff, I sure don't seem to
remember much. (elec. engr. background) A lot of it is easy to over
think. By now, the designs are so proven, you almost have to try to make
'em fail. I have a buddy who made one out of coat hangars and a 2 by 3.
It looks god-awful but dang if he don't get all the same stations I do with
my $50 Antennas Direct store bought. (grin)

About 1969, I used 300-ohm ribbon, solid copper wire, cardboard, and an
easel to make a Yagi antenna for one channel so I could watch "The
Avengers" without ghosts. It was a failure and I couldn't figure out why.
I noticed one site that liked the set-top double bowtie, said you'd get
better results if you bought a double bowtie "cat whisker" antenna,
intended for outdoor use, and used it indoors.
I use a four-bay bowtie "cat whisker" antenna like your example except
that mine has a one-piece screen. I used it outdoors ten years, then
put it in a closet because we had cable. In 1998 I got rid of cable and
tried the old four-bay indoors. I didn't like it.
Last year I got a Phillips amplified set-top antenna in preparation for
HDTV. It worked beautifully for VHF and UHF analog, but not digital.
I pulled the four-bay out of the closet and noticed the rusty rivets,
which I soaked in vinegar until I had continuity from each "whisker."
It makes a great indoor antenna for HDTV. If I'd thought to check
continuity ten years ago, I might have found it a great indoor analog
antenna, too.
Mine's equivalent to the Channel Master 4221, which is cheaper than
yours. If your riveted joints are more resistant to corrosion, I'd say
it's better than mine. (That's not to say the 4221's joints aren't
better than mine.)

Actually the cat whiskers are the equivalent of the bow ties. If you
take a line normal (90 degrees) to the centerline of the bow tie you
will have the electrical equivalent of a tuned wire antenna for any
given UHF TV channel.

Thanks for the antenna number. By golly, there are people who like it!

I rarely answer these, since I'm so lousy at them.
1463 is clearly an indoor antenna of some sort. TV, I'd presueme.
1462 is a hand truck. Or did you want to know what specific use this
configuration of hand truck is for? :-)
If I had to guess on 1461, I'd guess some sort of thurible that you blow
into to release the incense, but that seems bizarre.

I agree with this guess, though it's difficult to say how it was used, maybe
a science demo,or in a theatrical production, or just for fun.

My guesses:
1459 - Wire fence tightener; the groove on the thingy is slipped over
the fence wire, and then the wire twisted around the middle using a
wrench. The teeth serve to keep it from unwinding after tightening to
the right degree.
1460 - Appears to be some sort of a wagon hitch, with either a
cushioning spring or (more likely, in my estimation) an automatic
braking feature.
1461 - Fumigator? Some chemical placed in the can could be dispersed
and heated by blowing into the pipe.
1462 - Folding handcart for, ummm, maybe toting stovewood, although it
looks hard to balance regardless of what is toted.
1463 - Antenna; frequency band uncertain, but possibly UHF television or
the new fancy digital television.
1464 - I don't even have a faint idea what the intended use of this tool
is, but I don't think I want to be on the receiving end of it.
Now to see other guesses....

One Amazon reviewer tried five indoor antennas with HDTV. At first he
was pleased that the Silver Sensor got 19 channels. Then he found that
a simple loop would get 17 channels, and he had to keep moving and
aiming the Silver Sensor.
His favorite was the amplified Philips MANT510. I found it excellent
for analog, but it wouldn't receive all digital channels from a single
location. Even when I moved it to the best spot, reception often broke
up, and some days I might not receive some channels at all.
I've done better with a four-bay bowtie on a rotating stand near my TV.
Digital TV may ignore multipath interference that would cause ghosts
for analog, but I think some multipath interference that wouldn't be
noticed with analog can break up a digital train.

No, the bowtie shape is to give a broad frequency range (like 470-890
MHz). The impedance is determined by other aspects of the geometry.

1459 I cant figure this out but the "leesburg 'O'" suggest something to do

that resists loosening with vibration. Maybe on the rails?
1460 Cart steering yoke?
1461 opium pipe?
1462 like a sack truck but for carrying boxes rather than sacks.
1463 some kind of ariel. Cant guess what for I'm thinking radar but i very
much doubt it.
1464 could this be a kind of pitchfork? maybe for passing bundles of thatch
up to a roof?

Me too. At one time I used outdoor four-bay bow-ties with amps and
rotators. Then I decided that the quality of the shows wasn't worth
worrying about the quality of reception. Cable was worse because it
took me longer to determine that there was nothing worth watching.
Then I got an HDTV. I could get fifty channels if I rotated a four-bay
bow-tie above the roof. I could get the same fifty channels with the
same antenna indoors on a stand made from the pedestal of a broken
office chair.
There are a lot more worthwhile shows available to me because public
stations broadcast several digital channels at once. Better detail,
color, and sound make formerly boring shows enjoyable. Faces reveal
more character.
At one time I had reservations about Obama because I thought he had blue
lips. HDTV proved me wrong.
