Is the  ABBREE 771-GMRS good enough to start with?

It's working fine for me. AAMOF, the Abbree 771 UV is working fine on my ham radios as well.

Which outdoor antennas is this compatible with?  I feel like getting a nice big antenna and have it sit outside the house.  Pick up ISS, aliens, Klingons etc.

Klingons are aliens.

It would be compatible with any outdoor antenna tuned to the frequency you’re transmitting on, provided you use the right SMA to either UHF or N connector, whichever the antenna has.

Forgive my stupidity, but i need to be looking at UHF/VHF antennas rated for HAM radios at 108 to 509 mHz, yes?

What are you trying to accomplish?

Ham radio in the US, for the bands this radio is compatible with, is going to be 144-148MHz, 222-225MHz, and 420-450MHz. If you are transmitting because you have your amateur license, you would probably want a dual-band 2m/70cm antenna. If you are just listening, it's not as important to have a perfectly matched antenna. But typically an antenna like a discone antenna will cover a broad enough range to be useful from 108-509, for listening. If you are using the radio for GMRS the antenna should cover 462-468MHz. Again, a discone could be a pretty good antenna for 2m, 1.25m, 70cm, and GMRS. Or the Comet CA2X4SR. Both a discone or the comet will be external antennas. For built-in antennas a Nagoya or even abbree would be fine so long as it's listed as working for the bands you intend to transmit on.

 

There are a lot of other ham bands that are outside of this radio's capacity. But it covers the most common ones used with a Tech license.

My objective is to be able to hear as many signals as I possibly can.  I assume a more powerful antenna will help accomplish that. 

 

Now can anyone explain the difference between the AR-5RM and the UV-5RM+?

Although it’s possible to get a single radio that can tune almost everything from DC to daylight (cellular frequencies are blocked on receivers sold in the U.S.) and that functions well as a handheld radio for some of those frequencies, a scanner with a large discone would do a much better job as a home-rolled NSA listening post. It will scan the frequencies much faster.

Even better would bet would be a bank of scanners, each covering a section of the spectrum.  Understand that the RF spectrum is immense and there are many different types of modulation.  My Yaesu FT5DR does a great job for a handheld that can still serve well as a 2 meter and 70 cm transceiver and listen to FM and AM from 1 MHz to 999 MHz (minus cellular). But there are several gigahertz of frequencies above that.

But understand that antennas (or antennae for those who care) that are “more powerful” do so by focusing upon a smaller and smaller direction.  And antennas are most efficient around a single frequency.  It’s nice to have an antenna that can receive additional frequencies, but they do so at some cost: you have to include loading coils or traps or multiple elements that are tuned for different frequencies.

I’m sorry, but I don’t know the difference between the AR5RM and the UV5RM, but here’s what an AI said:

Quote

 

The main difference between an "AR5RM" and a "UV5RM" is that the AR5RM is essentially an unlocked version of the UV5RM, meaning it can access a wider range of frequencies, including potentially restricted bands, while the UV5RM is typically more limited in its frequency range due to regulatory restrictions;both are essentially the same radio with different branding and potential frequency access levels. 

Key points about the difference:

Frequency Access:

The AR5RM is considered "unlocked" and can transmit and receive on a wider range of frequencies, often including airband frequencies, while the UV5RM is usually more restricted in its frequency range. 

Intended Use:

The "AR" in AR5RM could be interpreted as "Assault Radio," suggesting it's meant for users who need access to a wider range of frequencies, potentially for monitoring purposes. 

Manufacturer:

Both radios are usually manufactured by the same company (like Baofeng) but marketed with different model names.

For portability get a Uniden scanner. It will scan 25-50 channels per second. The Baofeng will scan 3 per second. And the Uniden will cover from 10m (maybe even 11m) to 33cm.

 

For "as many frequencies as possible", an SDR. Even the lowly RTL-SDRV4 will pick up from 300kHz to 1.72GHz, with some antenna swapping necessary to get all that.
