Hi guys, I have just bought a farm, and have need to run about 3000' of feedline to get the antennas up to the top of the mountain in back of our property. I would like to put up a full wave 160M loo
but the question should I be aluminum wire, Paul, I had an open wire line about half that length made from #6 bare solid copper wire spaced 2-3/4 inches or less. Just the right spacing to make it 45
I used #4 XHHW stranded aluminum wire spaced 5 inches for Zo= 450 ohms. I have gone as far as 1000 feet with it. The loss on 40 meters is a few tenths of a dB. I don't see why you can't go 3000' feet
Paul, Use this formula to calculate your open 600 ohm Lecher line as a function of wire gauge and distance. Keep the line away from ground, otherwise you must introduce other factors as hight and the

Hi Group, Thank you for all of the replies. Lot's of good ideas were offered. I had another look around the property, and found that if I go the other direction, ie away from the mountain down into t
be of 10ga Paul, If your goal is to make domestic low-band contacts, you will probably be quite happy with a 25 degree take-off-angle. If you want to do any DXing, you may want to reconsider settling
be BTW, Paul, the other thing for you to consider is a remote base. If you can put some kind of equipment cabinet or shelter at the summit of your hill, you could run data and power up from your farm
be of 10ga AWG 4 is twice the diameter of AWG 10 (approximately), so if all things were equal (they are NOT, but bear with me), the surface area would be twice, so the resistance would be half. Surfa
current a test One further idea on the RF loss of ACSR power wiring... Take a look in the back of the NTIA report that just came out, and see what the folks in Boulder used to model power line wiring
I assume this is like typical drop wire for secondary power feeds or LV drops that "self supports". That type of wire has almost a straight lay in the direction of the conductor. Current flow in a wi
