Have both  versions. Attached you see what I did  with the antenna but

found

out the hard  way that when it rains  the concave bottom fills with water,
still works but not  as  good. So last night I made it flat with 3M Marine
5200 slow cure that  I have  extensive experience with from boating. Will

take a

full  week to cure but if it  does not work I can always remove it and

start

over

There is a similar approach using a small  "display dome" which is
basically a round bottom beaker kind of shape  designed to go on a wooden
base. It can just as easily go on a big cork or  stopper, or a disk cut
out of a HDPE cutting board.

Googling  "display dome" will show you copious choices. or somewhere like
"glassdomes.com"

Of course, if you have a supply of canning jars or  babyfood jars, then
you can use those. Nothing says the jar has to be  mounted with the axis
vertical. You could do it sideways (like a ship in a  bottle) to help
solve the "rain in the punt"  problem.

Is there a particular kind of food that works best? Perhaps strained
prunes has the best regularity?

Actually I used a home canning type wide mouth mason jar.    I thought
about a fish bowl but there are not threads for mounting.  Then I got
smarter and spend $29 on a real timing antenna and it''s been on the roof
for years.  The "jar on a stick" works but has very poor WAF.
