[DX] Yagi height and DX

[John Geiger]

I am currently using a Cushcraft MA5B mounted on a
tripod on top of a one story house-approximately 20
feet off the ground.  This antenna has worked well,
but I am wondering if I am hitting the performance
plateau with it.  I have 294 worked, including 4 new
ones this year-JD1o, PW0T, VP6DI, and XW0X.  

It seems that I am not hearing so well, though.  Last
night several 5 land stations reported SV2ASP/A as Q5
on 20 meter SSB, but I could not hear a thing.  Also
could not hear VK9L on 15 ssb that other stations were
putting on the reflector.

I plan on replacing the MA5B with a full size
tribander right after the KH1 dxpedition.  WOuld like
to do it before,but need to make sure I have something
up for that station.  HERE IS MY QUESTION:  WOuld
getting a tower and going to 40 feet make a hugh
difference over 20 feet?  Is it worth the trouble of
getting a tower and putting it up (do not look forward
to this).  Will that extra 20 feet allow me to hear
THAT much better?  

Figured I would get some profession opinions before
jumping into anything.  WOuld have to sell some gear
that I like to get the tower also.
