A Circularly Polarized Fm Antenna For The Attic

Whatjd i have a 2 5 story colonial w a slate roof so there was no way i was going out on the roof.

A circularly polarized fm antenna for the attic.

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. The lambda circular polarization antenna is for band i channels 2 6 and band iii channels 7 13. The development focused a top mounted circularly polarized antenna. 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. Fm antennas eri is the world s largest supplier of antennas used by broadcast stations. 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. 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.

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. In general this phenomenon will be exhibited in absorption bands of any optically active molecule. 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. E outstanding 1 pair am fm radio universal antenna 62 5cm 24 6 length 4 section telescopic stainless steel replacement antenna aerial for radio tv 4 5 out of 5 stars 436 6 99 6.

Circular polarization on 2 meters. There are a number of reasons why amateurs might want to experiment with c pol transmissions on 2 meters.
