I am nearly 70 years old. I got my General class when I was about 16. I have been inactive for 45 years but have kept my license up. When I was a boy, my dad helped me erect a beam antenna. It only cost a few hundred dollars back then! Now that I am wanting to get back into the hobby, I don't have the room for this nice beam but do have a small yard and home to play with. The antenna is the driving force that is preventing me from getting back into this. Thanks for the video.

Thanks for the video! I was a ham for some time, going up to Advanced class... then, due to various reasons Iwas unlicensed for about 10 years... then last june, after studying for several months, I took both the Tech test, and the Extra test! 85 questions in one test setting! I made it out alive, and with a Extra class ticket! :) So much for the background... Most of this material i know pretty well, but appreciate seeing it all from a different viewpoint... I would have like more info about Hex Beams... but with the time alloted, this is probably all you had time for that kind of antenna! - AI6XK

So if a dipole be it horizontal or vertical, bent, or even a 1/4 wave vert is half a dipole and uses the outer shield of coax as the other 1/4 wave if it don't have counterpoise radials.... is how its taught.... So it gets confusing where we run a 1/2 0r 5/8 wave vertical. the coil at the feed point matches the impedance and forces the 1/2 wave antenna to have 50 ohm in the center of antenna not at feed point causing it to radiate feed point to tip, like a center fed dipole. "They" antennas are best with the feed point half wave or a full wave off ground. So does this mean that I want the center of my 1/2 wave vertical a full wave off the ground or still the feed point should be 1/2 0r full???

Hi Dave. My name is Arthur. KD2pxe. I currently am new to ham radio I have a technician license. I'm living in a top floor 3rd FL apartment and using a homebrew J pole on 2 meters. It hangs from a hook in the ceiling. I would like upgrade to HF but cannot put up an outdoor antenna and have no access to the attic. I was thinking of putting a wire around the perameter of the ceiling. I was thinking of an acordian style folded wire for 20 meters. Do you have any thoughts that could help with this.

Hi Dave, Great video. Very informative for anyone starting out in the hobby. I've been around for awhile and have the classic trapped tri-band beam. It's 35+ years old and just brought it down for some much needed maintenance. It was on a Wilson TT-45 tubular crank-up that is also undergoing some repairs to make it last another 35 years. :-) Keep these videos coming. WB3BJU
@NullaNulla8 жыл бұрын
Nice video though I'd have made note that trapped verticals (the Cushcraft etc) are usually RATHER pricey :(. Each time I look they seem to sit around $1k AUD which I just cannot justify as much as I'd love one. If anything I need a good wind down/fall over tower of at least 40-60ft first (I know someone locally with 80ft but the mob that has it won't part with it until it falls down).

When viewed from above, do the two legs of the dipole have to form a straight line? If not, how acute can the angle be? In other words, can you do an inverted V configuration when viewed from the side that appears like an L (or even a V) when viewed from directly above?

No, but keep at least the center part kind of straight.

David I really appreciate your videos. I’m new on HF, and am using an Icom 7300, but with only a beginner’s basic vertical, and it’s not far reaching. Now that your video is two years old, I have the following questions. I am considering either the Cushcraft R-9, or High Gain 860. The reviews on the Cushcraft R9 seem better. Is there a better vertical than these two, that I’m not yet aware of. I have a roof eve mount ready for them. Bill Rhetts - KM6ESG
@davecasler6 жыл бұрын
I think you must mean the AV-680. The thing to note is that it covers only a tiny portion of the 80 meter band--you choose which portion. You might look at the less-expensive R8 and AV-640.

Is window line the same as what we used to call ladder line?
@davecasler6 жыл бұрын
Close, but not exactly. True "ladder line" has spacers every so often to keep the wires apart. Window line is just oversize twin lead, 450 ohms rather than the usual twin lead 300 ohms. To save on plastic, manufacturers cut lots of holes in the plastic, giving the appearance of cutting "windows" into the line. Very often window line is erroneously referred to as ladder line, so often the term has stuck.

Not so much. The Yagi itself is a resonant antenna, and off-resonant frequencies will be attenuated. One thing you can do as a ham is to shorten the elements to create a ten meter antenna.

In theory adding a linear will help you get out better. But be sure to check the RF safety guidelines to be sure that you and others aren't receiving too much RF. My antenna is about a hundred feet from my station, so even at higher power, I'm well in the safety zone. 73
