On a scale of one to WWV that's a four. Actually no where as bad as many I've seen. At least it has a breaker box, many don't.
What disturbs me is the lack of arresters. Of course these days the coax arrester costs more then the radio. If it's a single band shunt fed antenna, marine radio style, then they may have an excuse.
As expensive as diplexers are, you think they could mount them a bit better.
Serious lack of swastika graffiti, hacked off Heliax and WR90, internal bird dung and dead pigeons, plus the fact that you did not get bit by an otherwise harmless angry king snake... I'm not impressed.
Kudos to the owner for leaving a spare soldering iron/dummy load. That adds +3 Dbm to the score.
