ANT-450-RHR-SMA Antenna Dimensions Packaging Information The RHR series antennas are packaged 10 pcs per clear plastic bag. Bags are placed in cartons of 400. Distribution channels may offer alternative packaging options. 1.650 Counterpoise Quarter-wave or monopole antennas require an associated ground plane counterpoise for proper operation. 41.91 The size and location of the ground plane relative to the antenna will affect the overall performance of the antenna in the final design. When used in conjunction with a ground plane smaller than that used to tune the 2.024 antenna, the center frequency typically will shift higher in frequency and the bandwidth will decrease. The proximity of other circuit elements and packaging near the antenna will also affect the final performance. 51.41 For further discussion and guidance on the importance of the ground plane counterpoise, please refer to Linx Application Note, AN-00501: Understanding Antenna Specifications and Operation 374 9.50 2 .666 16.92
