AMATEUR-RADIO DX on 144MHz
2 x 9el 2.5wl (own design) with rotatable polarity (0°-180°)
The antennas are a 25ohms design and simply connected together after lambda 9/4 of 50ohm coax (25ohms to 100ohms transformer)
---------------------------------------------------------------------------------------------------------------------------------------------------------------             Some things still left to improve:
Still I don't have a balun since 2 years now, wich is called "disasterous" by a wellknown antenna-desinger.
You can decide yourself how  "disasterous" it is on my results or compare your receiving synchron with mine.
This is a minor problem in my opinion, but one day I'll use a balun to becalm my psyche ;-)
