  12. Antenna Relays

  13. These are great relays to use if you have the budget for them

  14. OK but I like to save $. I want to use one of these relays

  15. Receive configuration

  16. Transmit configuration

  17. Return loss (SWR)

  18. Compensation for VSWR(2 meters and below)

  19. Return loss (SWR) VSWR (return loss) is another problem that gets worse as the frequency increases • Uncompensated • 5pf added across NO and NC contacts

  20. Isolation • Common port terminated in 50z • Common port open One of the biggest issues with these relays at VHF is isolation The highest useful band appears to be 6 meters

  21. Compensation for poor isolation

  22. Compensation Compensation allows us to use this relay at 2 meters • Isolation (uncompensated) • Isolation (compensated with 650 nh) • Return loss (compensated with 5pf shunt)
