Jeff VE3CV" No, Jeff. I feed it with ~320' of Ladderline to a 4:1 Balun and then around another 150' - 200' of RG213 to the shack. I am on a hill here with sloping terrain to EU and most of NA ( as per HFTA analysis ) and it works gangbusters on all bands - even with LP - as I do not have an amp so I am stuck with 100 watts - which is enough or me :-) However YMMV Brian VE3MGY ________________________________ From: Topband <[email protected]> on behalf of Jeff Wilson via Topband <[email protected]> Sent: March 28, 2018 3:31 PM To: [email protected] Subject: Re: Topband: low inv-vee I have always used an 80m inverted-vee (66.6 ft per side) with apex at 50ft at top of a yagi-free tower attached to a steel workshop and fed with 450 ohm ladder line and shorted at the tuner in the shack to work as a top loaded vertical (35ft is actually vertical, rest of the feedline mostly hortizonal 3ft above a steel roof! Just worked JA8EAT with 100W on March 12 at 1040Z (thanks Yaz for LOTW confim and number 131 QSLd on topband...138 worked in 10 years). No 160m amp here....yet. Use 16 radials (100-130ft) and temporary winter 600ft Beverages and 200ft Bogs for RX. Helps being on a hill in the country as well. I always feel loud in the ARRL contests to the West Coast and KH6, but usually have to wait past 0300Z to work any EU even though I hear them at my sunset. So are the others (Brian?) talking about a true coax-fed 160m inverted-vee? If so, I'm interested!
