Just a guy building a fan dipole:

Guy Builds A Mult-Band HF Wire Antenna (Video)
- Thread starter Mudfoot
- Start date
Neat! I would enclose the rf choke inside of a larger PVC pipe with caps and SO-239 connectors and place a second one in the shack. He could make a NVIS antenna out of that as well. The other antennas made the new one not so significant. 
P.S. the MFJ-209 has a fancier tuner mechanism on it. If it's anything like my 207 then a freq counter needs to be used against it or zero beat it against the radio at said freqs

Looks like he shouldn't have been so cheap with the wire on some of the bands. They could benefit from being a bit longer.
that last one I built
17/15/12/6 needed no tuning on 17/15/6., and almost none on 12, i covers all those bands with NO tuner

Takes longer to watch the bloody video than to just build the fershlugginer antenna!
...that's for those old enough to remember the best days of MAD Magazine!

Wonder if a fan dipole can be made into a set of vertical/horizontal beams for freeband/11&10 meters?
Why not? One vertical and the other horizontal however you would likely have better performance running separate feedlines and switching them.
I seem to remember seeing a diagram somewhere of either a fan dipole (or was it a trapped dipole) as the driven and it used elements of all different sizes and spacing for the directors and reflectors... Some of them even did double duty on multiple bands. I'll have to see if I can find it again...

That could pretty much describe a vast number of multiband trapped yagis. My Explorer 14 has a trapped driver element for 15m and 20m (as wellas 40m as I added the QK-710 30/40m add on kit) and a "shock excited" parasitic sleeve element for the 10m driver and trapped directors for all the bands however it has a separate monoband 10m reflector.
It looks like insulated wire, if he did not allow for velocity factor will that account for it ??
