I don't think you're supposed to puncture the feedhorn at all. Had you broken the clear plastic window, you would have to order a whole new transmitter set. You might see a lot of problems in the summer, especially if some critters get in the holes.

This  is another known defect of the equipment....condensation in the feedhorn window, you can purchase that part separately with the o-ring. If equipment is under warranty, have Dway fix the junk.  My feedhorn acquired this problem about 2weeks of being installed with no rain in the winter....no where for the moisture to go....temperature changes alone will create the moisture problem. Another great enginering idea with no common sense involved?

Never actually seen it full of water, just droplets in the plactic window. Droplets are there when working fine, and of course they are there when its at a crawl....my guess is no big deal with the droplets.

Make your own weather cover.  If you have a bigger dish (.98m or 1.2m) like I do, it's a snap:

1. Get a bottle of pre-mixed window washer fluid. (I'm not kidding).
2. Cut off the top, so when you're done, the open end is the same diameter as the closed bottom.  Peel off the label, unless you don't mind your cover looking on par with a cool-whip-container-turned salad bowl.
3. The open end is now the exact size as to be a perfect fit over the feedhorn, so remove the  feedhorn/trans assembly as one unit, and CAREFULLY secure it in a vise.
4. Slide your homemade cover over the feedhorn.  No need to slide it on very far, just enough to where it overlaps by 1/4 of an inch or so.  Make sure it's level and true...not on at a weird angle.
5.Secure with an unbroken bead of caulk. I used a $1 tube of bath white caulking.
6.When dry, cut a 3 inch long rectangle shaped opening out of closed end.  Cut this so that when the feedarm is re-installed, this vent hole is centered side-to-side, but on the bottom end of the cover.  This does 2 things: (1) allows water to drain out that might be driven inside by a strong gale. (2) keeps condensation from forming on your cover by keeping equal the temps/dewpoints inside and outside the cover.
7.Re-install your feedhorn/trans assembly.

Mine's been like this from day one.  No loss of RSL, and keeps everything protected in wind,snow, and rain.

And yes, I have been called anal-retentive before, as a matter of fact.
