In software circularly polarization of antennas
I have an RSPduo which has true diversity capability. Now my question is whether or not I can use this diversity feature to select the optimal amplitude and phase contribution of the horizontal and ...

Would two perpendicular dipoles work to avoid polarization mismatch?
What would happen if you made an antenna consisting of two perpendicular dipoles tuned for the same frequency and connected to the same feed line? Would this work to avoid polarization mismatch loss?

Which way is a yagi polarized?
I am installing a yagi antenna that will receive signals from multiple omni antennas that are vertically polarized. Which way should the elements of the yagi point to match? Up and down, or horizontal?...

Dual Polarization Yagi Antenna for 10 m
Imagine that someone has built a 4 element horizontal yagi antenna for 28 MHz with elements insulated from the boom, and with the driven element not split in the middle and using a gamma match to set ...

What are the properties of the radiation of a magnetron?
It is commonly known that electromagnetic radiation from an antenna is polarized; the electric field is parallel to the rod and the magnetic component is perpendicular to it. What does the radiation ...

How Does the Propagation of H-pol E-M Fields Compare to That of V-pol E-M Fields (other things equal)?
A rather popular belief on this topic is that h-pol is superior to v-pol. Probably that is traceable to published "far-field" patterns over a lossy ground plane generated by Method of ...

Why do horizontally-polarized RF waves reflect better off ground than vertically-polarized waves?
It's a well-known fact among hams who use HF frequencies that horizontally-polarized RF waves reflect better off of ground than vertically-polarized waves. This explains why ground conductivity is so ...

Variable polarization Yagi using two antennas on the same boom, joined together with variable feedpoint phase?
I have been trying for ages to find a way to mount a 10 m vertical Yagi properly, so that the mounting pole doesn't stuff up the impedance and radiation pattern, and have had no luck so far. Apart ...
