Although I'm not very good with antenna theory, I've enjoyed reading the discussions of where what type balun should go, or not go, etc. in the KAT500 discussions. I still don't know how I would go about connecting my current antenna to a KPA500, so I thought perhaps some of you would have some input. Here's my situation/configuration: - Due to convenant restrictions, I am limited to a long wire (about 170') in an inverted "L" configuration (stealth situation) - Antenna feed point and ground/radial system feed point are together and about 50' from my K3/P3 location - Currently using an SGC-230 remote antenna coupler at the antenna feed point, with good quality 50 ohm coax coming into the house This configuration is working admirably on 160 through 10 meters. My original thinking on this configuration was having the tuner/coupler at the antenna feed point would help 1) keep stray RF away from the shack, and 2) minimize any feedline loss. However, with the 230, I'm limited to about 60 watts cw, and 200 watts ssb. Obviously, no KPA500 under my Christmas tree.
I initially was thinking there would be two versions of the KAT500, one model for indoor use, then another for remote/outdoor use. I could then replace the 230 with the remote KPA500 and then be free to purchase my KPA500. However, it appears a remote version of the tuner may be awhile coming. The question I keep asking myself is: Could I use the "shack" version of the KAT500 with my current antenna, and, if so, how would one hook everything together? Balun (1:1, 4:1, choke), or no balun? Coax, I assume would still be OK, but obviously would be higher voltages and a little power loss (but still probably OK at HF frequencies). Or, given the inverted "L"has to remain my antenna, is there still significant advantage to having the tuner at the antenna feedpoint - and I should simply wait awhile longer and see if there will be a "remote" version of the tuner? I love this reflector and Elecraft.
