Abstract
A new Flat Spiral VHF Antenna (FSVA) transmits circularly polarized RF transmissions only. The spiral antenna transmits from circular components only, forgoing transmission from any vertical or horizontal component. The spiral antenna may be integrated into an integrated antenna cover which fits into the top cover of a pit housing. The antenna cover and/or upper lip area of the upper lip of the main housing may comprise a distal barrier and a medial barrier used to exclude water and contaminates. Disclosed transmission systems offer high output and low power consumption and vitiate the need for meter readers to physically access a water meter or other meters.
