[Moon-net] Circular polarization?

[pe1lwt]

Hi Heinz,

It s up to you how you polarise you tx signal. I changed from linear to
circulair about a year ago and I do have good results since.(With 400w
into my 2x 10el xpol i get good reports( 200w in ideal polarisation).
Upto now i feel i have better result with the system as before ( 400w in
H or V) On my rx side i can change  from H to V or full rx control with
Linrad. Don't have the need for running the 8877 yet :)

Best regards,

Jurgen PE1LWT

Onderwerp: [Moon-net] Circular polarization?

Hi all
I Würzburg I learned, that some 2m-EMEers drive each part of theyr
X-pole antenna simultaniously from two separat PA´s. So they stay with
each PA within the powerlimitation of theyr country and prevent from
loosing 3 dB by splitting the signal into H und V.
Someone told me, he would use circular polarization in this way.
Due to my knowladge I would loose 3 db by receiving a circular polarized
transmission with a horizontal polarized antenna.
Wouldn`t it be better to feed the two parts of my X-pole antenna in
phase (or near to that) and let the antenna of my QSO-partner find out
witch signal, my H or my V, comes best for it?

Would be fine to get some answers.

   73 and hear/see you via the moon
