Hi, is anyone aware of who holds the patent for the PMPF passive dipole? And what does it cover? This type of dipole is typically bundled with parabolic grid...

Thks Joe, yep I think you're right. It seems Pacific Wireless has purchased PM's antenna product line, and now holds the patent for the PMPF dipole - if anyone...

... The P1dB compression point for the ERA-4 is only 17 dBm (50 mW), to maintain linearity you'd back off 3 dB from that point to 14 dBm (25 mW). The gain of...

Thanks Joe. The information makes a lot of sense but the Yagi stuff doesn't seem to apply or satisfy all my q's. Searching on the web for PCB dipole design...

Super Joe...thks, now how do I calculate the velocity factor of an etched PCB board? Can't find any notes on this. Btw, s/w I was talking about was like...
