Since the radiator comes with most radiator mounting options, there are only two additional choices.
Radiator Mounting Options
The LA-342 dual radiator mounting bracket allows you to mount two radiators together
(vertically or horizontally). This includes short lengths of coaxial RF and CAT-5 power cables.

There are two types of receivers to choose from. You may want to choose a combination of both types of
receivers. The stetho type receiver makes it simple to dispense the units and prevents cord tangling. However,
the stetho style for some guests is uncomfortable especially for prolonged time periods. The advantage of the
lanyard receiver is that you can use many types of different earphones. However this can make it more
complicated for distributing and the cords can become tangled. Each receiver comes with an alkaline
battery compartment (no batteries). You will need to decide whether to use alkaline AAA batteries (LA-363)
or a rechargeable battery pack (LA-364). Alkaline batteries will last about 30 hours while the rechargeable
batteries will last about 15 hours. If you order the rechargeable battery packs, you will need to order the 8-Unit
Charging/Storage Station (LA-350).
