Is it possible to work duplex with an Elk 2M/440EL antenna and two HT's, one programmed with VHF up link and the other programmed with UHF down link .... SO-50 for example?
Since the Elk 2M/440EL is designed for two bands, but only one coax connection, how would this be done?
Thanks

Get yourself a duplexer: http://www.radioworld.co.uk/mfj-916b_mfj_2m_70cm_duplexer
I am not sure which radios you should use but beware of de-sensing one with the transmissions from the other.
If using two radios an arrow without the duplexer is the equivalent as it has 2 feed points. And elk with a duplexer may work better than an arrow with no duplexer as there is additional filtering in the duplexer, which the arrow would not have, when using 2 radios.
So basically the elk has only 1 feed point, to use 2 radios get a duplexer. The arrow has 2 feed points, and has an option to add a duplexer to combine them to give one feed point for a single radio use. Having a duplexer in line may help with de-sensing.
