You may not like it but,  The 67 is not great in a parabola.
I recommend that you get the 62 capsule to use with your dish.
I started with a 67 and moved to a 62 and a dish. then another 62 and
k6 and then ......

Look at Walts site for the construction of a handle for a dish. A
clear Telinga dish will be around 75.US. Or you can go with Aluminum
for 50 or an Umbrella for 10.

You will find that the 67 is a great tool but should be separate from
a parabola it has a different use.  If you want to dump the 67 after
trying out the dish, the going price is about 75% of current new
which would pay for the 62 element which is cheaper.  That assumes
that you didn't scratch it up.

My 2 cents.,

Rich
