A BROADBAND DISCONE/CAGE ANTENNA FOR 5-30 MC

摘要

1. The discone/cage antenna is a self-supporting structure suitable for shipboard installation.n2. The cage circuit covers the frequency range 5-15 Mc and the discone circuit covers the range 15-30 Mcn3. A 3:1 standing wave ratio on a 50 ohm line may be realized through the use of simple matching networks.n4. Under some conditions the circuits may be excited simultaneously.
