Beste mede amateurs, Ik heb een vertical GPA 3 van Fritzel gekregen en die heeft een aantal (3) radialen. There is no GPA 3 afaik, I suppose you mean the GPA 30? Is er iemand van jullie die ervaring heeft met a. de GPA 3 I used the during a trip to TF and OY in 2001. It works, but that's about it. Not too much to expect from this antenna with 3 radials only, but I guess with additional radials it will perform a lot better. b. de plaatsing van de radialen At http://www.swschwedt.de/kunden/dm2ble/dok5-8.htm there are several diagrams which show the radiation pattern at different radial angles. Looks like 135 degrees yields the optimum gain. 73, -- Fabian Kurz, DJ1YFK * Dresden, Germany * http://fkurz.net/ |
