Replace antenna weather station

I make a modification antenna console-out remote sensor for better receiver-transmition signal ,after modification i have double distance signal .

Here it is console model before 2003 .Before modification it had for antenna over to PCB a square	I put it a red cable one-ply 0,5 mm for antenna 34,6 cm L /2 tuning wave 433 Mhz , from a trimmer over right place	Here it is the console after 2003 model .Before modification it was L/4 tuning wave about 17,3 cm antenna the right side


And here it is after modification with cable antenna 34,6 cm L/2 tuning wave	Here it is the original antenna over to PCB for out remote sensor before modification	And here it is the modification antenna out remote sensor with white cable one-ply 0,5 mm antenna 34,6 cm L/2 tuning wave


And here is ready with closed the plastic

Replace antenna temperature station

Here i make a modification antenna temperature station - out remote sensor for better receiver-transmition signal ,after modification i have double distance signal .

Here it is the temperature station .	Here i open it with 4 screws from back .	I put it a cable one-ply 0,5 mm for antenna 34,6 cm L /2 tuning wave 433 Mhz , from a trimmer over right place,i make a coil 0.8 cm diameter,for make the coil i use a screwdriver.


Here it is the out remote sensor from temperature station	Here i open it with 4 screws from back and I put it a cable one-ply 0,5 mm for antenna 34,6 cm L /2 tuning wave 433 Mhz ,i make a coil 0.8 cm diameter over a screwdriver.	And here with soldering iron i put the coil at trimmer the right side.
