revo adan: Dave was that a 1:1 or 4:1 balun?

Steve Tomlinson: Dave, Trying to get an NVIS ant. built for 40M. It will be 20' tall, and 8' at the end supports. 12 ga. stranded wire. I used RG58/U From the feed point, and included an rf choke at the feed point(used the rg58/U for that. The rest of the coax is RG8/U. The freq we are operating in is 7.240-7.290. Used 68' for length Inv V@(7.2). SWR was 3.2@7.0 /5.0@7.3. Made 3 cuts totaling 15", Now 1.5@7.0 /3.5@7.3. Can't believe I have to cut this much @ still 3.5 SWR@ 7.3. I'm setup on the side of a slope, and don't know if this is affecting the SWR. Any ideas??

Denis Carnochan: Thank you Dave. I live in a remote part of Alberta, Canada and there are no operators within hundreds of miles. I got my full spectrum licence a few years ago but getting up on the air has been very slow and often frustrating. The course may give you a licence but it sure doesn't explain how to set up and operate. Antennas have been my biggest frustration. I am not finished your videos yet but I have learned more in a few hours than all the technical reading in two years. I'm looking forward to seeing the rest. I must say that I know your passing information during the contest but I have no idea what you are saying. Perhaps another video for those new to the hobby. Again, Thanks. Denis VA6DBC

Seth B: For the rest of the world, that is not Canada, The Unites States of America or Mexico, 25.4 cm equals 1 inch, 12 inches per foot, 3 feet per yard, 39.37 inches per meter, or 3 feet 3.37 inches per meter, and the rest of the world can convert to our ass backwards archaic Standard Automotive Engineering units of length, just that easily. The US Federal Government officially went to metric in 1992. Unfortunately, everyone else, especially businesses, claimed it would create a financial hardship to convert to a standard that the whole rest of the world uses. That means when anyone works on a federal job all the plans are in metric but well over 96% of the materials are still in feet, inches, pounds, ounces, American Wire Gauge, rebar gauge, PSIs, KIPS, standard sheet metal gauges, SAE machine bolt thread pitch, etc. Even the paid engineers are too damned lazy or stupid to convert to metric & get it right more than about 75% of the time. We are "amateurs" and we KNOW "we" can do better. We do it all the time. The government decided to arbitrarily select millimeter sizes for electrical conduit. Rather than use decimals they arbitrarily selected whole millimeter numbers with total disregard for NEMA specifications for conduit, so some conduit sizes have inside diameters that are larger than their outside diameters. Think about one that for a minute. Does that mean we are supposed to pull the conduit inside out withe a special tool or machine, or are we just supposed to think these people are the same overpaid, under-qualified, ass-hats they have always been? Yeah, they are the paid ass-hats!

sktech76: Can you post the materials list in the video info? I plan to build this antenna soon. Thanks! 73!

Tommy N: Excellent video. You have more patience than I do.

Chigga Bits: Is that antenna a Rohn 25g Dave? What is the height of it. Thanks! Love your videos. I think I like building antennas and experimenting more than I do talking. 73s

petbytes: Thanks for posting this video. It helped me build and erect my 40 m V. de K6KNS

John Welcher: KM4KYA Thank you so much for the excellent videos that you produce. I am a hands on type learner and even though I understand the theory, the videos bring everything alive. You do a great job and very informative. I built the 40 mtr inverted V per your instructions and it worked first time. I am so pleased with myself that I had to let you know, You made it possible for me. Thank you for ALL you do and Gods Blessings to you. Jay KM4KYA <><

Tony Ridlen: I love this video I got to go on to QRZ.com to check out the available ham radio gear that is available for purchase while I listened to Dave and he built his antenna project.

Bob McGarry: Excellent video, thanks de N9oqu

Сергей Лебедев: Thanks Dave!
Thank you for showing how to make and adjust the antenna 40m!
I repeated the antenna 40m and your balun 1:1, this bunch works great !!!

Norman Davis: Instead of soldering the antenna leads to the center insulator, I have found standard plastic wire nuts do as good a job. I insulate the wire nuts with uncured rubber tape. Several of my dipoles using this method have been up for 8 years and have given me no trouble at all.

Ekawan Tamtama: Dave, thanks for your simple, nice and clear tutorial. 73 from Indonesia

R.W. LeBlanc: Dave I have a question Hope it don't sound dumb but i was wondering can the inverted v antennas have to be in an inverted v could you stretch it out horizontal 
or would they not work good as a horizontal instead of an inverted V

mykenwood830: Dave , Im putting up a W8AMZ G5RV Jr. in the inverted V configuration. My issue is that the ladder line and coax will have to drop down only about 3 feet or so and then go in a horazontal to my upstairs ham shack. Is this going to cause major problems with the efficiency of the antenna and or throw my SWR's completly out of wack ??

itsjimmyo: Dave you make great video's thanks.. I like your tilt tower, any chance on getting the plans on how to make that I do a LOT of welding and can't see buying one thanks again KF5AXY...

Bill Clark: Great video ..what a beautiful spot you have in KS..I am an FM enthusiast but know nothing about ham radio. I know a bit more thx

COPE Farms: Best how to video ever for dipole antennas. Thank you so much for sharing. Im sure it has helped many people like myself.

Railfanable 7-22-70: What kind of tower do you have and how tall is it?
