Anyway, if you did all above with it, It cover RF.
What do you mean RF? Are you talking about stray current or RFI? For both you need to ground your antenna, the coax shield, the power supply. Unfortunately, not a single house in Swabi has been grounded. I hired a noted electrician for my house's setup. He's been in the business since I remember. Upon my last visit, I experienced electrical shock on computer CPU, stabilizer, PS and radio. I went over to him and asked him if he has run a grounding wire. He said he would have done so if I had asked and that he has 'never' done any. How terrible!
