O Gauge Helix Kit: This 5 level helix was constructed and included the installation of the Ross Track. The purpose of this helix was to allow trains to be run from the lower storage yard onto the layout and the back down to the storage yard, eliminating the need to manually remove and add trains to the layout.
A High Gain Deployable L/S Band Conical Helix Antenna Integrated With Optical System for Earth Observation CubeSats ... 23 dB and gain of 6.8 dBi and 7.4 dBi, respectively, were achieved at resonant frequencies of 1.7 GHz and 2.45 GHz. The conical shape of the spiral antenna allows the optical system to increase the coverage area, and a simple ...

The conical helix is a curve generated on the surface of the cone by a point which revolves uniformly around the cone and at the same time either up or down its surface. The method of construction is shown in Fig. 10.13. 1 Draw the front elevation and plan of the cone, and divide the plan view into a convenient number of parts (say 12) and ...
A conical-mode helix has a traveling-wave current distribution and radiates a circularly polarized wave off the antenna axis. A spiral antenna with antiphase excitation radiates a circularly polarized wave in the direction normal to the antenna plane, with relatively constant input impedance over a wide frequency bandwidth.

It is shown that shaped-conical radiation patterns can be realized by extending the resonant fractional-turn quadrifilar helix to an integral number of turns, i.e., the radiated energy can be concentrated into a cone with the gain decreasing from a maximum at the edge of the cone to a local minimum at the center. This pattern shape is near optimum …
