Sennheiser Wireless: Sell or keep?

I teach technical theatre at a small private high school, and we normally use wireless lavaliers only once a year for three weeks when we do our musical production (Urinetown last year, Grease this year). We have a cast of between 18 and 30, and we generally rent wireless (Shure ULX) for each cast member in the show. Our director wants to make sure she has complete control over whose voices are heard well and whose voices are heard....less well. The system we rent usually comes fully racked with paddle antennas, antenna distro, connected computer with wireless workbench, the whole package.

However, I have a dilemma. At the beginning of the year, the IT department "discovered" a box full of microphone gear that they were planning to recycle, and luckily checked with me before they chucked everything. Turns out it was 10 sets of Sennheiser EW100 wireless lavaliers with receivers (6 G2 and 4 G3), all in the 500-650 mHz range, and one Bogen receiver and lavalier in the 470-490 mHz range. No idea when they were purchased or when they were buried in the server room, I've been here for five years now and had never seen them before. The ones I've tested so far seem to work fine, and when I found them I assumed we'd use them to offset our wireless rental needs for the musical and find ways to use them occasionally for other events throughout the year.

However, as I've been looking into it I'm realizing we're missing a lot of components to really make the system work properly. We have no paddle antennas or antenna distro, no rack-mount hardware (all the receivers were gaff-taped together in 2 stacks) and no real place to put a dedicated rack to store them properly. We also don't own the correct microphone elements- all the lavaliers have lapel mics, but we get Countryman hair mics with our rentals and would need to purchase or rent the equivalent for the Sennheisers (I've looked at budget versions from bodymics.com and Amazon or ebay, but i'm concerned about longevity and quality). The question is- would it be better for us to keep them and slowly put together all the pieces of the system we don't already own in order to use them in conjunction with whatever we rent in for the show, or should we sell them while they are still relatively new enough to be worth something? I don't normally get funding for equipment beyond what I'm able to scrounge from the show budget or use-it-or-lose-it leftovers at the end of the year. For our limited needs during the year, is it really worth it to invest in the Sennheiser system? How much longer will it be legal to use the 600 mHz band? Before I knew we owned these, I thought it would be ridiculous to invest a large amount of money into owning wireless mics for our limited actual needs, especially given the uncertainty with potential frequency auctions. Now that they were dropped in my lap, I'm not sure.

Thanks for your thoughts!
 
My experience is that the Sennheisers basically last forever! I have about a dozen that I use frequently, and even the old G1's still work great. "C" band is out, "B" band may be on borrowed time, but that may be years yet. "A" band is still going strong. The only parts that I've had to replace were the mics (ME2) which get broken by idiots, and the occasional whip antenna. Stuff is still easy to get. I did have to touch up some solder joints on the old style G1 belt packs. After enough drops, the connector for the display board can develop solder cracks where it is attached. (symptom = no display, but still works)
On the other hand, the resale value of used Sennheiser on Ebay is very strong! G1's usually go around $200, G2's around $300, and G3's easily bid up around $400. So, selling them and using the money to buy a new system is also a strong option. Whatever you do, don't chuck them! Be like burning a stack of $100 bills!

Antenna distros and the paddle/shark fins are not necessities. They are nice to haves though. In budget strapped community theater land, of the 3 companies I've worked with who own wireless, only 1 opted to get the antenna distros (and then they paired them with incompatible antennas. AT D band 1/2 wave antennas don't work so hot with AT I and C band mics. That has been rectified.). Otherwise I'm used to dealing with 16 SLX or 20 Sennheiser ew100 units in full porcupine mode with 2 1/4 wave antennas per receiver. No reception issues, even at ~75' from the stage.

Those bulky ME2 capsules work just fine in the hair, just needs a bit more finesse to hide them. The biggest weakeness I've found with the sennheiser stuff is the 1/8" connection. I've had locking rings come loose on the transmitters, and a lot of the ME2s have had their insulation break right above the molded strain relief.

Wireless workbench knows how to coordinate Sennheiser gear, so you don't have to worry too much on that front, but you would need to work with the rental company to make sure what they give you won't interfere with what you have.

Speaking of those connectors, they do fail a lot, but I replace them with this guy. (It is a threaded locking connector that fits.) Do suggest potting them after replacement. http://www.mcmelectronics.com/product/DISTRIBUTED-BY-MCM-AV17501-/27-8180

thanks for the recommendation JD! How would you go about potting them? Hot glue inside the connector before closing it up?

We're going to do some testing with the 1/4 wave antennas and the ME2s, but my director (who is in charge of the budget) gets leery about experimentation with sound equipment. She'd prefer to just rent the full setup and be done.

The gap in the back of the connector is large enough you could shoot them full of hot glue after the case is on. I recommend putting about 2 inches of heat shrink tubing over the end of the wire itself. That cuts down on the amount of flexing near the connector. Also, when I use the packs, I loop the wire down and around the body clip and then tape it. It's common for users to damage the wire by dropping the body pack as they are putting it on or taking it off.
