My antenna is currently mounted on a jury-rigged PVC pipe support that sticks out of an upstairs window then up via a T-connector and more PVC pipe, placing the antenna barely above and outside of the gutter on the south side. That’s as high as I can get it with that setup due to weight and unweildiness. My own roof effectively blocks the north and another nearby 2-storey house’s firewall blocks much of the east. (To the west and northwest there are hills and mountains: not much I can do about those.) My antenna’s about 5.5 meters high by my reckoning.
I’m unable to access my roof to put the antenna up topside so the only way to get it higher would be to put it on a mast, at least 7 meters long, mounted on a re-enforced concrete fence post near my house with wall mounts, which I already have. They can accommodate from 1 to 2 inch masts. The longer the mast the better up to 10 meters or so as there are also some 3-storey houses not far away whose roofs I’d also like to try to “see over” if possible.
The mast would have to be strong enough to be self-supporting and not need guying in moderate breezes as I don’t have room for guy wires: the fence is only 1 meter from the house on the south and is just on my side of the property line so I’d only be able to guy the mast on the east and west sides anyway. It would also have to be easy to lower quickly by one person in case of higher winds or thunderstorms (I live in typhoon alley.) A telescopic pole of some sort would be ideal, I think, but all I’ve found are carbon fiber fishing poles that collapse or “un-telescope” from the weight of the antenna and LMR400 almost as fast as I extend the sections (I just tried one yesterday using a temporary mount for the pole.) I think some sort of locking mechanism would be necessary to prevent that. I haven’t been able to find any proper masts either, not even shorter ones.
Wondering if anyone has any ideas for something I could use as a mast?
