-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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?

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. Paul, KD7HB |
