Re: Topband: 160m polarization and elevation angles

Hi Jim The omission of the words ‘inverted vee’ in front of ‘dipole’ for Tom W8JI’s antenna up 300 feet high was a slip of the keyboard at my end! I used to work Tom regularly back when he had the antenna up and helped him with comparative signal reports. When he was doing signal

Re: Topband: 160m polarization and elevation angles

Greg, In concert with HA7RY (Tomi), one night I was monitoring OH8X while the monster Yagi was still up. At Tomi's QTH (in Hungary) it was very loud. I could barely copy it in FL. I worked EU stations that were much stronger. I think the antenna was too low and there was too much high-angle

Hi Carl, OH8X was active for some months when I was making Qs with Eu, in particular OH. I never heard them at all, although I have no idea of exactly when they were QRV. My guess is that if their monster antenna had produced results, they would have been a lot more active. We can certainly

Topband: 160m polarization and elevation angles

Polarization - As Jerry K4SAV stated, the electron gyro-frequency plays an important role on 160m since our ionosphere is immersed in a magnetic field - it also affects ionospheric absorption and refraction. For those of us at mid to high latitudes, vertical polarization on 160m is *theoretically*
