In the not so distant past, TV antennas by necessity where large things.....for good performance on channel 2 they needed to be about 8 feet across the back eliments.
just about all antennas came folded up in boxes or bags and required assembly.
now with the digital restack and the abandoning of band 1 & 2 for television in capitol cities and more or less all reigonaly TV going UHF, TV antennas have go a hell of a lot smaller.
a lot of TV antennas now come completely assembled.
On VHF...for most capitol cities, the predomonatng design these days is the twin beam log periodic....a good high gain VHF only example like the Fracarro LP4F is about 2 feet across the back and about 2 feel long and pretty light...and it gives about 9db gain....and cheap as chips
On UHF there are Three antennas that are known performers the yagi, the log periodic and the phased aray or cake rack.
The Yagi tends to need a rear reflector so does not pack flat
The twin beam log periodic like the Fracarro LP4F and it coppeis comes assembeld and is about 2 feet long about a foot wide and produces arround 10Db gain on UHF band 4 with no electronics..if you want compact....you will not get more performance in the space than one of these.
The phased array.....they look like a cake rack with a couple of bow tie eliments in front is a known good performer...like the WISI EE06 and its coppies.....but they are less compact than the log periodic for performamce delivered.
As for the T antennas that look like a couple of bits of conduit glued together in someones back yard.....they have been a joke in the aerial business for years.
you could build the actual aerial part out of a coat hanger in about 10 minutes and they are dependent on the amplifier for any performamce that they produce.
If you need an amplifier....buy a decent one from a decent manufacturer like Kingray.
There has always and there will always be joke antennas being sold in the caravan market......unfortunately lots of people are convinced that they are wonderfull.....sorry...they just arent.
Buy a decent aerial and a decent booster if you need one.
cheers
