430 and 1200MHz collinear antennas
JA1PTO
 
Built 430 and 1200MHz collinear antennas.
Left is for 430MHz, 8 components, 2300mm long. Right is for 1200, 12 components and 1250mm long。
   

N type connector for 1200M.

430M collinear is built into exentsible fishing rod. More than 2m is too long for storage or carry around so fishing rod is good for portable.
Coax connector can be covered in the rod itself. Water proof system.
