I'm going to try to put together my own raspberry pi. So I have been collecting parts for it as frequently as I can. I have not yet had the chance to put it together but I have examined these parts and they appear to be exactly as described and will made. The connections look sufficient and is gent and this should apply very easily to the build.

Needed to replace antenna on a receiver for a garage door opener that was just using a straight piece of wire for an antenna. These antennas have more than just a piece of wire inside and provide noticeably better reception due to more signal delivered to the receiver.I'm quite satisfied and would recommend for anyone needing a good antenna for a device operating at 315mhz frequency.
