BTW, that works! I once had a 100 ohm/300 watt resister. For kicks and
giggles, I cut wires for an 80 meter dipole, connected them to either end of
the resister like a cobra head and ran coax to the wires. The resistor was
actually between the shield and center conductor with the wires extending
outwards. The antenna worked on 80-10. When I checked into the 75 meter
net, I did not have a great signal, but I was readable. Ten meters was open
and I made several contacts, but when I removed the resistor, the receive
signal improved incredibly! The SWR was under 3:1, but I don't know by how
much. I had a tube rig and that was all I worried about. Today, we want
1.5:1 or better.
BTW, I DON'T recommend that for a QRP antenna unless it is an emergency.
Then a dipole would be better.
FWIW.

Having a resistor at the feed point is about like putting a dummy load at
the end of the feed line and hanging wires out to radiate.
