design of a new Antenna: Loading with coil, making balun. Need Help!

Primary Question
So I was hoping I could get a simple vertical 7MHz antenna to be less than 2-5m. I was thinking loading the antenna with a coil could work but i'm not sure. If anyone has any good designs, I'm up for giving them a shot.
Along with that, If you guys have documents explaining how to design a Balun and Dipole properly, that'd be great because although I know how they work, I don't know how to make one (what ferrite core to use, etc.)
showing any math corresponding to any answers on design would be much appreciated!

Off topic
Are my VHF-UHF antennas any good inside or is it just rule of thumb to have them outside? because i have a V dipole outside for satellites (works like trash though... But that's just my poor design and use of no balun.)
