Here's another home project for show and tell:

The transformer is a 1:1 wound on a type 43 "squaroid" core. 
Measurements at work show a maximum loss of 0.3 dB at 30 MHz, and since 
I don't run more than 100w, core heating isn't much of an issue.

This tuner feeds a 110' inverted vee @ 43', fed with 600 ohm ladder line 
to the base of the house, then via another 8' of two RG-62 sections in 
parallel.
