fotograficzny wyzwalacz radiowy do lamp błyskowych - zasięg

http://satsleuth.com/RF.htm Parę schematów może cos podobnego będzie do tego urządzenie twojego :) Niby coś znalazłem z RF-01 bo chyba takie oznaczenia ma ten wyzwalacz ale widzę że to nie to ale coś blisko :) A antena to nie to po prawej gruba ścieżka a na końcu kondensator? nie wiem czy dolutowanie jakiegoś przewodu druta coś da ale można spróbować:) http://www.hoperf.com/pro/RF01.html Ciekaw jestem na jakiej czestotliwości i na jakim paśmie pracują takie lampy błyskowe i wyzwalacze http://jap.hu/electronic/rf.html I jest i Antenka :D tak jak myslałem do tej ścieżki przymocowana :) http://www.flickr.com/photos/makelessnoise/1956119247/ http://obrazki.elektroda.net/50_1241998668_thumb.jpg tylko że dlugoś anteny musi być odpowiednio dobrana ten układ prawdopodobnie pracuje ma 433MHz i jak widać juz ktoś to robił tu :) http://www.elektroda.pl/rtvforum/topic1091833.html

DESCRIPTION
In low-cost RF applications a whip antenna generally provides the best
overall performance. In many cases, however, the use of a whip is not
practical for cost or cosmetic reasons. In instances where a designer is
looking for a blend of easy concealment, low cost and good
performance, a helical antenna is usually the optimum choice. The HE
series from Linx delivers exceptional performance and ease of use,
while maintaining a cost factor appropriate for high-volume
applications. Linx helical antennas are precisely wound and matched to
provide the lowest possible SWR at the operational frequency. In
addition, the antenna diameter and inter-coil spacing are optimized to
provide a wider than typical bandwidth.
