(*) NOTES:

• The quarter wave antenna requires an adapted ground plan (metallic surface). Not to be mounted on PVC cabinet!
  
• The shortened quarter antenna (helicoid) is less effective but can be used in small space.
• The half wave antenna doesn't require any ground plan so it could be mounted on a plastic case for instance.
• If the antenna needs to be deported and fixed on a pole, an appropriate antenna with low loss cable (ref CFP10-NM-NM-L) and N connector must be used.
• Yagi antennas are directional antennas : more the gain is important and more the direction angle is narrow. Take care of the polarization when installing: if there is an amni-directional on the other side (vertical), the blades of the Yagi must be positionned vertically.
