Icom 7300, MYANT EFHW 1080 inverted L, 50' rg8x generic feed to bulkhead, generic rg8x patch from bulkhead to 7300. I rarely have any swr to worry about. Never anything approaching 1.5. Been very happy. Life is good. So I decided to try my hand at rolling my own coax for future projects and convenience. Built 4 separate patch cables each about 4-5 ft. Bought generic crimp-on pl259's from ebay. Bought some Davis RF RG8X at HRO and a handful of their generic connectors. Watched youtube instructions carefully from several sources. Practiced. Took my time, followed instructions to the letter and was very careful to getting it right. Each cable passed the continuity test on the multimeter. Time to test. Hooked up to 7300 and each of the four I made shows an increase in swr of at least 1.5 or greater on most bands. All four. So I hooked the original patch back up. Same as before. SWR barely discernible. Frustrating. Am I missing something here?
