Anyone have any experience with this sort of antenna? Let me know
what it is I'm doing wrong.

One needs to understand how the 300 ohm twinlead
transforms impedances and why a 4:1 balun is probably
not a good choice. One could model this antenna and
feedline with the free demo version of EZNEC
available at eznec.com
