The antenna bottom reinforcing support is an important structural design to ensure its stability and performance. In the prior art, the base of metal material is bolted with the installation position, and a hole needs to be punched in the installation position before this operation. This operation is limited by the specific material of the installation position. In addition, the completely fixed installation makes the antenna column have no buffer space when subjected to external force in adverse weather conditions. The external force will cause the bolted connection to be loose, which forms a safety hazard and increases the maintenance workload. Therefore, there is room for improvement. UTILITY MODEL CONTENTS
