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 ...

Now because of curiosity I took the case off and saw that on the HF input it has a built in Upconverter... My question is whether or not I need to do any frequency Shift in the SDR# software I have. Radio...
