Mike, I would be concerned about using these small relays for non-resonant antenna switching where the impedance at the switch point may be wildly away from 50 ohms.
This is the relay I use to switch tuning networks at non-50-ohm points: http://www.deltrol-controls.com/products/relays/power-relays/900 Deltrol is the brand you get if you order from McMaster-Carr but all the big relay manufacturers sell these open frame relays. I also bend the relay contacts for wider spacing as recommended by N6RK in QST (page 66, May 2009 QST Hints and Kinks, "Increasing Relay Voltage Handling"). Open contact gap of 0.5 inches is readily achievable.
