|There's been some mention of HF antennas for 40m. I highly recomend reading the link below on feed line losses. Carl may have posted this link B4 but just in case, here it is again.|
It shows the differences between ladder line and coax as far as losses go. There are charts and plenty of text. Does anyone want one antenna for nulti-bands? If so this reading is a must.
