Hi Dani,
Hope this helps.
"Question 1: Will you advice buying myself a prepared parabola / mount / ha=
ndle like the Telinga one, as I suspect? Or are there other choices / brand=
s? cheaper? I know the umbrella/wok thing :) but is it worth it?"
A1: I have not heard of aftermarket brands of parabola mounts, so either bu=
y the one that is designed for the particular dish, or DIY make your own. Y=
ou will get much improved performance from a hard surface with a precise pa=
rabolic curve than a fabric surface with an uncertain curve.
"Question 2: Is the parabola approach designed to be used with JUST omni mi=
cs? Are other caption patterns allowed, or is it senseless to use direction=
al mics here?"
A2: No, yes, perhaps. Try it with what ever mics you have on hand. But if y=
ou need to buy mics for your dish, start with omnis.
"Question 3: Aware of how a smaller mic will be attached to a parabola in m=
uch an easier way than a shotgun mic... Is it possible to use the parabola =
approach with shotgun mics like mine (sennh mkh 416) pointing towards the c=
enter of dish?'
A3: The capsule membrane needs to be positioned in the focus of the parabol=
a, so your mic is probably too long to fit. The tube might need to extend o=
ut through the mounting hole, and that does not seem very practical to me.
Q3b: "Does this enhance directivity for a shotgun?"
A3b: That depends on your definition of "enhance":) Once you put it in the=
dish, I think it is no longer a shotgun mic.
"Question 4: Has anyone ever tried to use a shotgun like mine with a parabo=
la behind it, both pointing in same direction? (opposite way, unlike small/=
lavalier mics pointing to center of dish) > Will this improve results of a =
shotgun? What do you believe this experiment will cause? -if it has any sen=
se-"
A4: Yes they have tried it, but no I have not. The mic will no longer be a=
shotgun mic, but an altered parabolic mic. Remember, the capsule membrane=
, not any other section of the tube, needs to be positioned in the focus of=
the parabola. Your experiment will reveal to you the truth.
What recorder will you be using? There are inexpensive options for omni mic=
rophones that might work better than your mkh-416 in this application. This=
would keep your shotgun mic free for the close up work it is designed for.
