I'm working QRP (5W max) and I'm construction my own antennas. I've
read that antenna efficiency can be degraded by "high ohmic connections"
(especially deleterious to QRP ops). I'm assuming that we shouldn't
make potato-sized solder joints when assembling the antenna. So, I was
wondering what would be the best way to connect various parts of the
antenna?

Example: I've created a 4:1 balun based on Ron's (VK2DQ) description in
his article "Understanding and building the OCF dipole." The toroid
windings had to be connected. So, rather than twist them together (they
are 18 AWG) and solder them, I laid the pieces side-by-side (abt 1/4")
and solder them together. Is that a "high ohmic" connection? If so,
what other way could the pieces be soldered together w/o creating a high
ohmic connection?

For other parts of the antenna (e.g., the feed-point) would connectors
(quick release, ring type, etc.) be better than a solder joint?

Thanks,

Well, I recently finished installation of a 160 meter lazy quad,
horizontal loop, fed with home made 600 ohm feed line. All connections
have crimp type terminals that are also soldered. The plastic was
removed from the terminal before use. Then the terminals are bolted
together. I change things quite often and needed to have an easy to
disconnect the feed line from the antenna and house. Seems to be
working just fine.
