I’ll go out on a limb and advise you to build a simple half wave dipole for your chosen band, fed by coax, supported at the centre feed point by a telescopic pole. If you include links in it to allow multiple band operation that will make it more versatile. But to start with you can build a single band antenna just to get the hang of it.
The dipole is the basis of all antenna theory and all antenna gains are referenced to the half wave dipole. Every ham should own and/or build one early in their experience of ham radio. When you use something else you can compare them with your dipole. And the secret is that not many will be as good and few will be better.
If you add links to the design (perhaps when building a second antenna) you’ll effectively be building something very similar to the Sotabeams band hopper.
You can safely ignore the purists and not use a balun. Don’t worry about what anyone says. Slight differences might be made by using a balun on a coax fed dipole but the dx worked by mine says it is not vital for success. My dipoles (without baluns) have allowed me to work the world using 5w from an FT817.
As for fitting the same antenna into your backyard, that is another matter. Noise pickup in suburban lots is notoriously high at present and will probably increase. The main solution to that is unfortunately to operate from somewhere else, such as SOTA summits. Unless your home is in a uniquely noise free environment, you may experience a lot of interference on almost any ham band, but especially the HF bands. In my experience the end fed antennas pick up much more local noise than a centre fed antenna, but I may have been unlucky. your mileage and your S meter noise readings may vary.
Look at some blogs of successful activators for antenna ideas. You don’t need to restrict yourself to commercially built antennas, they are much more expense than a home made one and don’t work any better.
I suggest looking at vk1nam.wordpress.com to start with, my friend Andrew (whose current callsign is similar to mine) has published many of his antenna designs there.
If you decide to build your own linked dipole, a handy calculator for wire lengths for each band is included in the sotamaps website linked above under “Mapping”.
