Apr 22, 2024 · This page details the construction of an easy-to-make collinear 360 degrees omni-directional, vertically polarised, antenna for 802. Around 1954 to 1956 he was asked to develop a gain vertical antenna by Communications Products Company of New Jersey. All due respect to Carl and his wonderful J-pole, this little gem will actually outperform his an-tenna because it’ll get your signal out farther due to its higher gain. Dipole antennas (or such designs derived from them, including the monopole) are used to feed more elaborate directional antennas such as a horn antenna, parabolic reflector, or corner reflector. ~~~~~~~~~~~~~~~~~~ I would like to share with you my findings and my design of the well known vertical collinear antenna, by looking at the work of two other Feb 16, 2021 · A diagram is shown in the figure on the right.
