I am trying to build an antenna tuner for my 2m (1m + 1m) dipole antenna. It has a 1:1 balun and is connected to a coaxial cable which is connected to my radio with an impedance of 50 ohm. I can't hear all the FM and even short wave station reception is very poor.
After some research I got the idea for an antenna tuner which can be used for both SW and FM.
The LC circuit and the air capacitor I need for impedance matching is not available in my area. Hence, again after research got the idea of capacitance multiplier with variable resistance.
I don't have much idea/knowledge on this circuit. Can anyone help me on this antenna tuner unit? Which chip can I use for the above functionality?
Edit 1: Seems like both SW and FM tuner in a single unit is more complex and will be beyond my reach. I want to focus only on FM 88MHz to 108MHz, what would kind of antenna should I use and what should I do for impedance matching?
