To successfully operating a CHA F-LOOP or a CHA F-LOOP Plus from indoor, fews things must be observed.


  1. The quality of RX and TX of the unit will depend if a metallic material has been used to cover the roof and/or the walls of the building. If it's the case then the performances of the unit might be very low as barely nothing will get in or out of it.
  2. If you're living in a high density area and your antenna is located at the first floor or even worse at the basement of the building, the RX and TX will also greatly suffer. So try to get as close as possible from window or an outside wall.
  3. Install you unit as far you can from noise generator devices like large computer, flat screen TV, games machines like X-Box and PS4 and AC system.
  4. If you live in a two story building then operate the loop from the upper higher floor if possible. You'll reduce the noise level and the RF blockages produced by all the stuff that is a ground level and which will prevent your RX and TX to get out properly.

With a good antenna location you should be able to achieve the following with a CHA F-LOOP or CHA F-LOOP Plus
