Spec: Item Type: Wideband Directive Antenna Material: PCB Mode: R101C Basic Parameters and Their Explanations: Frequency Range: 730MHz-6.5GHz The R101C antenna has good transmission and reception performance throughout the entire frequency range. The standing rate is less than 2.0 and has good gain. When the frequency range is exceeded, the gain and return loss of the antenna will rapidly decrease, and the usage requirements will also be correspondingly reduced. When the standing ratio is less than 2.5, it can be used up to 700Mz to 7GHz. Polarization Method: Linear polarization The R101C antenna is a linearly polarized antenna. The polarization direction is vertical, which is the same as a vertical monopole antenna. Gain Rated: 7dBi The gain of R101C antenna slowly increases with the increase of frequency. At approximately 800Mhz, it is approximately 5dBi, at 2.4GHz it is approximately 7dBi, and at 5.8GHz it is approximately 9dBi. Return Loss: 10dB The input impedance of the R101C antenna is 50 ohms. When the 50 ohm impedance is connected to the source, the fluctuation within the frequency range is less than 10dB, and the corresponding standing ratio is about 2.0 Power Capacity: 5W When using R101C antenna as the transmitting antenna, we recommend that the RF input power does not exceed 5W. Short term use can exceed 50W without causing damage to the antenna. Directional Sensitivity: R101C has good directional performance and small side lobes throughout the entire segment. It can be used as a direction finding antenna. The horizontal direction of the antenna pattern is relatively wide, with a -3dB width of approximately 60 °; In the angle of altitude direction, the directional pattern is very narrow, with a -3dB width of approximately 40 °.
