it might help to get clear wieu between the tx an rx
the other thing that you can do is to add rf amplifer on antena aut ( i f it detachteble type and if not just replace it )
the output of ev 100 is 30 mw , so this is very low when you have allot of people crossing the line

that one increase the signal 75 times more and will give you about 300m (1000feet ) working range
cheap hings cost money :-)

I wonder if they make a longer Tx antenna,
or if one could be fashioned? -->>>
the longer antenna will do eny thing or just reduce the rf out , each tx have spesial lengh depends on the friqvency

I've never had a dropout with my plug-on and microphone taped to the top of the DJ's Speakers. That normally is above everyone's head and line-of-sight to the receiver antenna.

Perhaps my competitor is not getting his up high.
I see that the antenna on the G2 does not appear
to be removable.
So, let me get this straight. Peoples' bodies being between the Tx and Rx can interfere with
transmission? It's not just metal objects that
can affect this?

Well, I tested some mic's next to blasting speakers.
They were the DPA 4060 lav (with 48V phantom),
the Samson R11Q dynamic handheld, and the
on-board PD. I tried various degrees of attenuation
(10, 15, and 25dB). In the end, the DPA came in in
third place. It needed 25dB of pad not to distort
the PD pre's. Second place was the PD with 15dB
pad. First place was the Samson, with 10dB of
pad.
In the end, none of the recordings turned out
particularly well. I did notice that over attenuating
seemed to have a stifling effect, so it seems
best to use the minimum necessary.
If I wanted to get a line off the DJ, what type of
connector would I most expect? Would imagine
it's mostly 1/4" or RCA. Can they mix to mono?
I would guess not, so would it be best to take
the left or right channel? Do they usually cooperate
in giving a feed?

almost every mixer have mono out , so you can take the feed from that point , or just take 2 rca and mixe them together .
if you recording from the speacker use dynamic mikes .
its not a problem to replase the antena with detachtable type you can place sma socket ( its just cost money:-)), all objects which between the antenas are redusing the range and not only metal ( that is making the
problem much wors )
another thing ,every aria have different rf users , so the mike that working well in one place can be not good if you use acupid channels ( tv stations , police , ambulance , army comunication , ets ), so its not a bad idia to check the rf befor the shoot ,since it can change even you was ok last time
