When he house was renovated i took the old one down after 20 years abuse... still worked well.
I had a spare new one that was put up now, not planning many trips on the roof at 71 years young.
Expensive? yes 175 euro here from Hofi, that still makes hem with original parts.
Saying up here through storms winter/summer and 20 years without problems is good in my book...
For 10/12/15 i use an Imax 2000 5/8 on 10/12 and a half wave on 15.
160 has it's own vertical.
That way i can chose between FD-4 horizontal and vertical on 10/12/15, both have no problem with my normal 100 watt or if i use the Heathkit SB 1000.
Build like a tank....;)
