| Page 2. 24.4.39 WSO/027/B. Messrs. Bentley Motors (1931) Ltd., DERBY. for your/ products. There is a patented "Booster" unit on this aerial which increases the signal up to six times, and this is exclusive to MOTOROLA. Experiments have been made on your cars, and this Aerial is definitely the best that can be used, and has flexible mounting brackets to prevent the aerial from being wrenched off should it come against any obstruction.
