I have used TV RG6 for over 30 years. Usually 50 feet or less and it handled the output of my SB200 amp well. In Ecuador that was the only coax readily available and it worked well. I recently bought a roll of 250 feet at Walmart for $30. Checked the loss of 100 feet and was about 1.5 dB at 145 MHz. Not as good as open wire feedline but for coax very workable. Cannot beat the price. I also have used the "F" connectors up to about 600 watts with no problem and now find BNC conn at Home Depot made for RG6 Coax. There is a lot of discussion about using RG6, usually from those who have not used it but have heard it is not good. It is definitely better than RG174 but heavier. I have been fortunate to have found good RG6 but I always test it before use. It works well in an ugly balun also at HF. I usually use the 25 foot lengths found already made with connectors on each end. I have used two runs in parallel, center conductors of course, to feed a doublet for multiband HF. 50 feet lengths feed my 6 and 2 meter verticals. Dr. Don W4BWS
