I hastily threw together a 30 meter Delta Loop this summer in order to get
KH8SI in the log for a new one on CW. Using the formula, the resonant point
came out 10.105 mhz (great, first try!) but the feed-point impedance is 79
ohms. 

What is a good method of matching this antenna to 50 ohm coax? I don't want
to use ferrites. I'm using a line-flattener in the shack now, but I robbed
it from another project, and I need to return it.

This antenna is a real "keeper;" I was able to bust the pile-up on 2nd call.
The apex is a 50 feet on an 80 foot Rohn 25 tower.

Thanks in advance for any suggestions.
