Okay, that's what I have been discussing with Mark.
In his situation, and it sounds like for most of your
situation, the VHF active antenna I described in schematic
for (a subset of the AA7C) would do for 30 Mhz and
up.
What is your HF frequency of interest?
I have a "wiring closet" with the hangar wall immediate to that
location. I would run the coax out an up the wall to the antenna
mounted at the edge of the roof, right straight up from the wiring
closet, and house the enclosure in that closet. Was looking at the
Ramsey AA&C for that purpose, but with an externally mounted
antenna. Or is there a better alternative? Oh, I live in a 60 x 60
metal hangar, and reception inside is pretty poor.
Active antennas like the AA7C pretty much expect
for the 'antenna' to be a conductor exposed to
signals of interest with no intervening feedline.
The conductor is expected to be short with respect
to any resonance at frequencies of interest. In
other words NOT suited to drive a transmission
line . . . hence the need for some active device
to adapt the poorly performing, short antenna
to a feedline.
You only mentioned VHF signals . . . for
30 Mhz and above, the antenna Mark is
needing sounds like what you need too.
Your situation does not sound like an AA7C
inside wired to an antenna outside would
be the best opportunity for the AA7C
to do its magic.
A 'whisker' stuck up through metal roofing
with an active adapter box on the under side
sounds like as close to ideal for an active
antenna as you can get.

Sure. There are lots of HF active antenna products
and DIY designs out there. Are you looking to build
or buy one? What's your range of interest for frequencies?
What is the nature of the proposed outside antenna
and feedline?

Hmmm... Huntsville, AR
Here's where your TV stations are with respect to the airport. They are all a good distance away but not on one common mountain top. All of them except the PBS station (which is on a high VHF channel) are on UHF.

It doesn't look like there are a lot of strong signals so overload of an amplified antenna shouldn't be a problem. I don't think a single antenna is going to do everything for you though.
I'd look at RV amplified TV antennas for the TV. They're usually a disk shaped thing that will have some sort of mounting that can be done to the roof of your hangar. I usually don't like these antennas because in hilly areas they can compromise reception because of multipath (receiving bounces that are slightly out of time with the main signal). In the old analog TV days this would show up as ghosting. Now with digital it degrades the signal because of (apparent) jitter. But they are easy to install and use.
The AM/FM and Air radios can all work off a garden variety car radio antenna. All of this will have to work with radios and TV sets that have antenna connectors that you can attach the antenna's to.

Bill brings up some important points that should be
considered in this discussion about unobtrusive antennas.
The 'active', omni-directional, untuned antenna for
UHF/VHF is never capable competition for directional
antennas specific to a frequency.
My impression of design goals for the beginnings
of this thread suggested that signals of interest
were adequate to used on a hand held transceiver,
a portable FM receiver or perhaps a portable TV
receiver EACH OF WHICH uses some form of attached,
whisker antenna.
In other words, the task was to work around the
shielding qualities of a steel building. The reasons
for adding transistors to the base of an antenna
is two-fold (1) allow a VERY high impedance, non-resonant
whisker to drive a relatively low impedance coax feed line
and (2) add some gain which tends to overcome (a)
losses in the feed line and (b) augment a marginal
signal.
If you stand on the roof of your hangar (or other
RF unfriendly building) and experience useable
performance from the hand-held, then the active
antenna I've suggested will EXTEND that usefulness
into the building.
Adding gain to burrow into atmospheric noise
is another game entirely . . . a game that can
be played by specifically tailored active antennas.
Just be aware that the laws of physics are inviolate
and the act of adding some transistors to the
base of your antenna is not a universal solution
for weak, noisy or otherwise over-the-horizon signals.
So to watch that station in Fayetteville from
Huntsville is a hop of 22 miles. No big deal IF
you can 'see' the transmitter from the top of
your hangar. If you can take a hand-held up and
get adequate performance on this signal source, then
the simple active antenna has a high probability of
meeting your needs. Otherwise, plan-B is called
for . . . have you considered Netflix? We dumped
cable a couple years ago and never missed it.

Great reply...yes, for entertainment, I watch Netflix almost exclusively. But even my weather radio doesn't pick up well in the hangar, unless he front door is open. And with the severe weather we have been having the last few years, that is not a minor consideration. And I do like to watch the news, either morning or evening. Since I live in the hangar and am always at the airport unless traveling, I would like to monitor the Unicom frequency for traffic - would be nice to have transmit capability, but not necessity. I have been given a tower for TV antenna, but it will be a major pain to ever get permission to erect it, even though I have the beacon tower in my front yard. Not to mention the time an expense to put it up. No more than I watch TV, it would be nice to have an easily acquired and installed antenna that can go on the roof right above my electrical closet.

This is the limit of what I want to do. A friend has his travel trailer right beside my hangar and has great TV / FM reception from his little crank up antenna on the trailer, which is what gave me the incentive to join this discussion.

See remark about the travel trailer above! So... if I build the Groundplane Antenna - Model FA2 in from the site you provide at the first of this thread, mount it on a short piece of pipe so it will stick up three or four feet above the eave of my hangar (there is no hangar overhang) and mount it securely to the wall of the hangar, that should provide me with good reception for my limited scale of usage? Will I need any kind of amplifier? Is that what you mean by an "active" antenna? Signal boost through the coax to the distribution box?

We live 100 miles from any area of population

If you need only VHF/COMM and Wx, then consider the

You can transmit on that antenna and it will

Keep it simple. Use a car radio antenna for AM/FM/Air. If you go out and
buy a broadband (like a discone) antenna that's kind of over kill. The
scanner antennas from Radio Shack rain elements after a high wind or ice
event. If you want a cool discone antenna, but a good quality one with
solid stainless steel radial rods. Radio Shack's radials are thin tubes
crimped onto screw fittings.
But like I said. for under $20 buy a car radio antenna and drill a hole
in the edge of the hangar roof with a step drill.
