Did this video help you?

Anthony Duffy: Great videos, love the no nonsense approach..Thanks and 73's

David Eisenberger: David excellent video! Thank you for taking the time and your patience to go in depth. It is appreciated! I do have one question for you. Since your not using a Choke Balun or 1:1 device, how are you keeping Common Mode Currents off your feedline?tnx es 73's de K8KEM (also a david)

Rob Losie: Wonderful video! I've been a ham since I was 16yrs and were now 57yrs. Made many dipole and inverted-V antennas but sure had all my question answered here. Wish I had this video back in the day. Going to blame you for having me out in the garage this weekend. Thanks so much for sharing.  Rob Mn.

Alan Hughes: i use to build antenna,s in the army we used stainless steel cable ,any advantage using copper wire , stainless can be pulled up tight and lasts a lifetime.

Musa Anderson: Nice and useful video Dave...

Greg Newberry: nice vid. thanks Dave for taking the time and having the patience to show newbies like me how to go about this procedure. Excellent work.

anthony zelina: what is that old telephone rotary sound??? like dialing ?

Rob Fern: Dave,

got a link or part number where I can get those butt end connectors? Thanks!

glen wells: you don't need more pockets you need a couple of boy scouts that are working on a merit badge to help you. just got my first HF today will make one of these within a couple of days. thanx for the vids

Seth B: This is exactly what I put over the top of my house, when I bought my linear amp. Now I can run 1200 watts SSB. It will do the legal limit, but I am not looking forward to the day, when I need to retube & settle for Chinese tubes.

David R: Nice video was that a Hustler 5 band vertical that i saw in the garden?

Jon Unwin: Great video Dave very informative I'm going to build my own antenna in the next couple of weeks using your advice. best 73s from across the pond

Arnold Ruiz: Great Vid Dave, I learned something.. I want to build your 40M dipole but want to mount it on a roof top in NYC. Do you think it will work ok?? Thanks again for the vid... Awesome... N2YDC

Aleneski Kalashnikova: Very nice build. Great!

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!

Zoo Monkey: Excellent video. You have more patience than I do.
