[Moon] Polarisation

[Håkan Harrysson]

Hello,

Maybe not any idea for a newbeginner as me to report this as most of you have been doing so much already. ( but i had fun doing it,,)


I did send a little letter last week about measuring cirkular polarisation.


I have today  built me a little RF probe with just one capacitor and one diode connected to my multimeter.  I after this connected a  gamma matched DE to the probe.


I then put out some low power and walked away 100 feet from my antenna.  I was very positively surprised to see that i could measure exactly the polarisation as the measured value dropped down as quich as i turned the DE just a little.


I think  i will be able to measure  my cirkularity on the antenna with this small cheap equipment.  I will also try to measure how the  RF field strength changes when i try to mount my X yagi with a aluminiumpipe to see how much i loose in radiation.  (i have problem with high wind so i need to go from glasfibre pipes to alu pipe if it is possible)
