WebDec 31, 2024 · Article One – The plan. This is the first of three DIY articles on building a 160 meter, 3/8th wave, inverted ‘L’ antenna. The original goal was to throw up a wire that would do 160 meters and with the use of a tuner be able to make contacts on other bands. My current G5RV antenna runs east/west so the lobes naturally extend south/north.

Web160 meters is +12 VDC, 80, 60, 30 meters is 0 VDC and 40 meters is -12 VDC. Base Loading Philosophy Since the series combination of the 160 meter loading coil and 160 meter shunt coil has a very high impedance at 60 meters and higher, it was simpler to just leave them in the circuit for all other bands. Drawings WebSep 21, 2024 · $\begingroup$ Top loading may be the cheapest way to get more current flowing over the entirety of the vertical radiator, with the added benefit of reducing the capacitive reactance you have to match. Think of the combination as simply bending a longer radiator. This can be as simple as a wire from the top of the "radiator" to a nearby …
