Please go to http://groups.google.com, and search this newsgroup for
postings I've made which contain the phrase "mismatch loss". Hopefully,
that will explain it.

What about mismatch loss?

Assuming 50 ohm coax, the vee should be closer to 50 ohms.

The 73 ohms of the dipole would result in a small mismatch loss.

One could droop the dipole down about two-thirds along the way to get
close to 50 ohms - at least that's what my EZNEC says - been a user
since the first version.
