The VHF transmission-line rocket antenna consists of a transmission line terminated in a short-circuit at each end and comprising a variable capacitor connected in series with the horizontal radiating element near the short-circuit at the opposite end from the feeding point. The antenna was designed and examined by electrical performance tests, environ- mental tests, and a flight test. The results were very good and showed the antenna's practicality. The antenna has the merits of having an overall length of less than a quarter wavelength, good antenna patterns, being light weight, small in size, and giving good performance under the environmental conditions. It is tunable over a wide frequency range with a low voltage standing wave ratio by using only a variable capacitor.
