RF Venue Antenna Distro w/Sennheiser ASA-1?

I'm looking at integrating an RF Venue Diversity Fin Antenna into my Sennheiser Rig. Currently I'm running 12 Sennheiser G3 Receivers off of 3 ASA-1 power/antenna distro's. The RF Venue needs (or they claim) one of their Distro4 units. Should I be able to get the Distro4 to talk to the ASA-1's? The ASA-1's are sending the receiver DC power over the BNC cables, and I'm worried about looping that back into the Distro4 and frying the unit. The Distro 4 is sending power out a separate line than the BNC cables and has a handy switch for enabling power out. The ASA-1 are always running power and there doesn't seem to be an end user switch for disabling power. Anyone have any experience getting this gear to work together?

RF Venue should answer a simple question: Is the antenna a DC short or a DC open? If it is a DC open, there would be no problem with the ASA-1. If they won't answer that, or they say it is a DC short, then use a DC block between the antenna and the distro. You could also take an ohmeter and measure the antenna yourself.

Here is a DC block. Put one on each antenna.

Thanks! That link returns a bad result though.

And the answer from RF Venue:

"Hi Chris,
Thanks for reaching out to RF Venue,
The Diversity Fin is open DC, no need to worry about it getting fried, we have done many Diversity Fin installs on Sennheiser ASA-1 Distros without issues. Please let me know if you have any other questions.
Best, Rob

Thanks again. Was able to do a work around with existing gear and RF Venue's Distro interfacing properly with the ASA-1's. Final set up was Diversity Fin into Venue Distro 4. A/B Antenna outs fed ASA-1 antenna ins. No DC power on those lines and everything was good.
