Fine workmanship ensure long service life. Thanks Pete, that answers his question and the linked article has helped me understand a bit more. More refinements More refinements A friend has run long Beverage receiving antennas using this method. I've got two of these lashups here at the shack, one for 20M, one for 10M, as alternates to the ft magnetic loop up in the treetops.
Grounding and Receiver Noise
At each position I would make careful measurments of the resonant frequency and SWR with an antenna analyser. It made by ABS material and heat shrinkable sleeve. You'll need about feet of wire for this antenna plus appropriate length of coaxial cable. This is barely significant. Turns out the wire I had hanging from a clip from the patio cover had a bare spot and was touching the metal gutter.

Please provide a valid price range. In my college days, long ago in San Diego, the two storey apartment building right next to campus has easy access to the roof via decorative cinder blocks with footholds in them. I done this once a few years back, and it worked surprisingly well. Because I park in a parking garage. You will need to shorten the whip using the cutting chart that includes the spring length. Ground at the antenna end will be whatever the antenna thinks it is, while ground at the receiver end will be whatever the receiver thinks it is.
Remember that proper grounding practice for electrical wiring has very little to do with RF grounding. Originally Posted by Sonicadventure.

The formula used for this antenna is the same as the Multiband Long Wire above: I was thinking of using plain wire with some plastic spacers to give me the appropriate width between the wires. The receiver will, of course, respond to any voltage input that differs from its chassis ground. One antenna per band stacked.
