Smoke damage to aerial from chimney mount?

Supercell

My chimney has a Sky type dish for Freesat and I just installed an aerial over that (on a separate mount) with a combiner and all is working fine.
However I do light a fire in the living room most weekends and the smoke is likely to blow over the aerial occasionally as i had no choice but to mount it over the dish, almost horizontal with the top of the chimney.

The chimney is pretty solid so not worried about the position from a structural point of view more but i'm wondering if the smoke is likely to damage the balun in particular as there is a small circuit board there?

Is this a big issue? To be honest if I had to replace the aerial every five years or so i could live with that as putting the aerial up wasn't very hard to do (drilling the mount and cabling up took far longer).

I could mount the aerial somewhere else but the neighbors wife likes to moan about unsightly cables around my house spoiling her view (not joking) and I really could do with keeping neighborly relations as calm as possible so don't want to go down that road if it can be avoided, 20-30 euro every 5 years or so for a new aerial would be far preferable.

You should get more than 5 years out of it. Smoke wouldn't be a problem but the combination of heat and moisture will take its toll over the years. I always try to avoid installing an aerial or dish on a chimney for structural and corrosion reasons.

So do I, but I was in Reykjavik, Iceland, a few weeks ago and was astonished to see scores of 1m+ dishes (some of them motorised) and glass fibre ones at that, mounted on chimneys. They looked as tough they had been up for some time too. Maybe they build better chimneys up there:) I think their weather might be a bit more severe too.
As regards smoke....there is sulphur in coal smoke and this, combined with moisture can make short work of unprotected aerial connections (sulphuric acid!). A good dollop of silicone grease on the terminals can prolong it's life.

Thanks excollier, i was thinking of wrapping the plastic casing (around the balun) in amalgamating tape but didn't do that as i was worried about over heating in summer sun, silicone grease directly on to the board and around the bits of the f connector that hasn't tape on it sounds like a better solution so will go with that.
