HF for receive only or transmit and receive?
HF antennas can be constructed with some wire cut to the right length and coax. If you want to transmit, you need an antenna tuner or BALUN.
Antennas need to be tuned for the band if you want good performance at low transmit power.
Antennas need to be matched with the transmitters' antenna tuning ability.
What rigs will you be using?

It is the Yaesu FT-991A (100 watts). It already has a built-in 160 - 6 Meters High Speed Automatic Antenna Tuner. I guess that means it matches?
I have looked at getting a 4:1 Balun and making my own.

Yaesu FT-991A Review: Next Generation Compact HF Ham Radio
The Yaesu FT-991A is a compact, all-band HF base station that is small enough to be used as a mobile rig or to be used for dedicated field operations.

We used two different antennas that worked well with this radio. For HF, we liked the MFJ-1778 G5RV Wire Antenna and for VHF/UHF we used an MFJ-1729 Magmount antenna.

I think I am going to go with a simple center fed dipole antenna. The Radiowavz DX40 Short. I spoke with the ham at the ham store and he said this has excellent performance on 40m through 6m. I won't get much on 60 or 80 but I can live without that.
I'll mount this in my attic in an inverted V configuration. Attic is more than long enough (needs 37 feet) and top of attic is around 45 feet. He felt I would probably get South America and Europe with this setup. This is the type I would build myself.
I also got another antenna for 2m and 70cm. This one I'll mount outside my window I think. Comet GP-3 - Dual Band 6ft Base Antenna 2m/70cm UHF
DX 40 OCF SHORT
Band width:40m,20m,10m Typically with out a tuner.
Antenna Length: 37 ft. end to end UV insulated stranded wire.
Suggested minimum antenna height: 25ft
Power: 1500w SSB/PEP 200w CW

DX Off Center Fed Windom | Radiowavz.com
The Radiowavz DX (OCF) Windom is a off center fed dipole antenna that exhibits outstanding performance on multiple bands typically without a tuner.This antenna is ideal for those who do not use a tower and beam. It's also ideal for those who want a high performance antenna with world class DX...

Bookmark this page. You will probably need it with an antenna in your attic...

The antennas are a good choice.
The HF antenna in the attic can work, but it is placed close to RFI emitters like LED lights and electrical wires. These can raise the receiver noise level and make it difficult to hear weak signals at some frequencies.
When the antenna is close by, transmitting can interfere with televisions and consumer electronics, which are poorly shielded from RF emitters.
If you were a hermit, you could turn off all the lights and not watch TV when you wanted to communicate. You may find your Ham activities interfere with what others want to do in the house.
There are ways to remediate the interference. You may have to move around the wires in the attic away from interfering sources. So, I would leave things flexible and moveable until you find a good setup.
Your transmitting causing interference with your neighbor's TVs or radios is a separate discussion I hope you do not run into.

I got both antennas in and am planning their installation. Also getting ready for my Santa gift on Wednesday!
Meanwhile I have been working on my radio shack. Well, at least radio "corner". This was a junk storage area now it has a real use. I'll need to route the antenna RG8X wire through the wall (I'll need to buy more). One of those bookcases will be cleaned out of most non-ham stuff this week.

Just got into radios. Found some old ht750 and 1250. Got a bcd436hp and baofeng iv5rm+
I almost went for my amateur license back in the early 70's, I was about 8-10 years old. Back then they still required Morse code knowledge, I just couldn't get too excited about that.
Currently have the GMRS license, here in NorCal, since the Camp fire burned down the town of Paradise, GMRS has become popular for emergency communications. Our neighborhood watch even went as far as setting up our own repeater, and the Butte County Sheriff runs some repeaters with public access.

I don't have my antenna up yet so I did not hit the transmit button. But, I set my Baofeng to the frequency you see on my base station and sent a quick message which was received LOUD and clear on the Yaesu.
