A Circularly Polarized Fm Antenna For The Attic

In general this phenomenon will be exhibited in absorption bands of any optically active molecule.

A circularly polarized fm antenna for the attic.

We entered the business of manufacturing fm antennas in the earliest days of fm radio and continue to serve the changing needs of fm broadcasters with the industry s best products. Circular dichroism cd is the differential absorption of left and right handed circularly polarized light circular dichroism is the basis of a form of spectroscopy that can be used to determine the optical isomerism and secondary structure of molecules. Satellite communications typically involve a vhf uplink in the 2 meter band and the azimuth elevation of the receive antenna on the satellite is constantly changing making c pol ideal for best illuminating. What i did was mount a conventional outdoor antenna upside down in my attic so that the elements of the antenna are closer to the floor where it is wider and the rotor and mast are secured to a tie that extends between the rafters where the attic is narrower.

It has comparable loadings to the familiar horizontally polarized super turnstile. Discreet and easy to disguise this antenna combines the best of both worlds since it features the power and range of a big outdoor antenna with the style consciousness of a smaller indoor antenna. High power peak voltage rating power rating of 40kw for single bay broadband for multi station operation stainless steel elements radomes or integral deicers optional excellent circularity 1 db for both horizontal and vertical polarization the dcr u features a pressurized tap point and 4 balun which makes it specially designed to handle the high powers and. There are a number of reasons why amateurs might want to experiment with c pol transmissions on 2 meters.

With a signal range of up to 60 miles multidirectional signal reception and vhf enhancement rods for channels 2 13 this affordable antenna is one. Fm antennas eri is the world s largest supplier of antennas used by broadcast stations. Low vswr superior vswr band width and minimal weather related vswr problems fully pressurized internal feed and welded feed connections high input power capacity modular construction facilitates easy installation and repair. Circular polarization on 2 meters.
