[NLRS] Open Grid dishes

[Barry VE4MA]

I use 1/4 inch hardware cloth on my 4 ft tropo dish and have feeds for 2.3,
3.4 & 5.7 in it.  The mesh is OK for 5.7 tropo

Follow up question. I have a prototype aluminum grid dish made for 2ghz. I
was considering covering with fine mesh wire. I would suspect this will work
for 1.2 and 3.4?  Comments?
