I live and clean roofs here in Tampa
http://www.roof-cleaning-tampa.com/2012/10/tampa-roof-cleaning-contractors.html, so I get to see a lot of antennas, LOL
In this part of Florida, we have a lot of retired, elderly Hams. I am a "Kid" of 58 years, but many, if not most of my Ham Radio Friends are in their 70's and 80's!
Many of these fellow Hams are winter residents only, and have big, multi tower systems, back home somewhere. I would have to say THE most popular multi band directional antennas here in the Tampa area, are w/o question the K4KIO Hex Beams, followed closely by the Tennadyne T6 and T8 Log Periodics.
Because we have so many non Ham, retired people here in the Tampa area, we have people with nothing better to do with their lives then Bitch!
Quads are scary looking things, to a non Ham.
Of all the antennas I have mentioned, the Tennadyne Logs are IMHO the Least "Hammy" looking. LOL, they kind of look like a glorified TV Antenna, once they are up on a tower.
Speaking of Hex Beams, you almost don't even need a tower to support those.
Both the Tennadyne T6 Log, and the K4KIO Hex Beam, are in the 600 dollars price range.
The Interlaced Force 12 Yagi that Tom, W8JI mentioned is a great antenna. However, they are near double the cost!
Plus,, I knew several who waited for Months to actually get a Force 12 antenna!
Tennadyne seems to always have T6 and T8 antennas, ready to ship, and so does K4KIO, I am told.
I have cleaned many a roof here in the Tampa area, that had either a Hex Beam, or a little Tennadyne T6 Log mounted on it, with a small roof tower.
I have never cared for a roof mounted tower, and of course, they are not possible on the many Tile Roofs we see here in Florida.
But, we see them on the shingle roofs here, and I hate to clean them!
Basically, we use a chlorine bleach based solution, and must be careful not to rust the roof mounted towers!
My competitors in the roof cleaning business here don't care if they rust the towers, But being a Ham, I do care!
I have developed a petroleum jelly type rub to coat the tower legs with, that protects the roof mounted tower legs from the chlorine based chemical we use.
