Hello Nigel
No experience of the Amberwood, or making/using my own molds etc.
However, the Wildlife Sound Recording Society might still have some
ready made parabolic dish blanks still available at about 25 pounds
each (if I remember correctly). I bought two at the beginning of
Message: 2007.
Subject: Sorry I do not have the name of the contact at the moment but if
you go the The WSRS website and look at past newaletters you will find
it there. I have used the "WSRS" dish to develop the latest
"wide stage parabolic" currently being tested. Plenty of details are
in recent posts by me.
In addition to using a made up dish you could make your own using
segments mdrawn up from a formula ( which is conveniently downloaded
ready to use:-)
I made one myself (using corrux - estate agent sign material) and it
performs OK.
Have a look at messages #26274, #22283, #22806. Also you might want to
do a search on tk7859, corrux, parabolic reflectors either singly or
linked.
