    I remember a stealth antenna for scanners made with foil tape , it had a horizontal piece with three or four virtical pieces of different lengths Yagi style , these were wrapped around a piece of drain pipe and then the assembly was put inside a larger diameter drain pipe with a top cap and a bottom cap with a hole and a piece of plastic mesh at the bottom to keep out insects and let condensation out ,this was then fixed to an outside wall with drain pipe wall clips

    I've used that type of copper foil tape to make antennas! I made a two-element bow-tie antenna for my TV, and a dual-band fan dipole for 2m/70cm for my handheld - both using plastic laminated sheets. I didn't try soldering. I used small nuts and bolts to connect the coax. It was much easier and provided better physical support. SWR for 2m/70cm was decent - about 1.5 or better on both bands. Pretty cool!

    sure you check it with an ohmmeter to be sure it is conductive (most duct tapes are not).

  • @robertvandersanden
    @robertvandersanden 3 роки тому +1

    Hi Gil, as an electronics engineer I work with lead free solder often. It requires attention to work well. The most important is that lead free solder has a narrow temperature window in which it works well and it is lower than with solder containing lead, more like 260C where leaded solder works better at 350C. If you go above 260C with lead free it burns and doesn’t stick. And it ruins the tip.
    Clean your solder tip, wet is with a big drop of leaded solder if you still have some to recover the tip. If the tip looks nice and shiny again, solder with lead free at no more than 260-280C.
    You can buy tiny tins containing a solid kind of paste in which you can stick your tip to recover it. I have it called Tip activator. Handy to have when your tip needs some TLC!

    • @robertvandersanden
      @robertvandersanden 3 роки тому

      @@RadioPrepper Yes I know. That’s because your tip is burned. You need shiny fresh tin on the tip to get the solder to melt. And once your tip is fine again (I hope you can revive it at all) you will notice that it works reasonable at lower temperature. Although leaded solder is still much more convenient. I fully agree on that. Lead free is best for automated well controlled soldering machines.

    • @robertvandersanden
      @robertvandersanden 3 роки тому

      Just don’t be tempted to crank up the temperature if it doesn’t melt, stay at the low side. And for myself I prefer a bigger tip so you get better heat transfer at lower temperatures.

  • @scottgilbert7927
    @scottgilbert7927 3 роки тому +1

    Bonjour Gil - great idea! I would say that you needed to shorten the antenna length for resonance in the 2m band because of the glass. I have a lot of experience with making wire vertical antennas on fiberglass or PVC supports, and always have to shorten them well below the theoretical free space length to make them resonate a particular frequency. The adjacent dielectric material, be it glass or plastic, makes the antenna longer electrically. One never knows how much to shorten it by, but you have to go through the process of tuning the antenna manually as you did. The standard free space formula 468/F for determining the half-wavelength is a starting point, but always gives too long a length for the actual antenna as in this case when a dielectric support material is so close. The glass may also absorb some of the rf as well, but not much.

    I used some alarm tape used to detect glass breakage to make a dipole for uhf to put on a celebrity radio commenters home office. First I determined the window was not coated with metallic film. He had a plastic grid in the window to imitate a pane glass window. So I was able to hide the antenna and feedline behind the plastic grid. The grid helped hold the feedline at right angles. I Used about 25 watts and received an excellent noise free signal used for several years. It was almost totally invisible which was good for aesthetic reasons.

    Nice Gil. I have used that copper tape for a number of antenna projects - I use the wide 10cm copper tape, taped to a fibreglass mast to give a broad band vertical antenna. I have used the wide tape strapped to a hola-hoop for a magnetic loop antenna. For your vertical dipole, you should have the elements in a V shape - about 120 degree angle to drop the impedance closer to 50 ohms and give you a much better SWR

    Your soldering iron carbon build up is what's making your life super difficult. Try a tip tinning compound. That with a brass wool soldering sponge helped remove all the carbon from my tip and it made a huge difference, even if I used lead free solder.
    Don't fall into the trap of sanding or eroding the tip material, you just need to clean the carbon off. It takes a while but I saved my tip and it works well now.

    Dear Gil, I suppose your window frame is PVC type. If so there is a pretty nice metal frame inside and it "kills" your improvised antenna. This tape antenna will work as a normal dipole if you have a wooden frame and no metal parts embedded in it. For sake of the science you can play with a piece of plywood or PVC with a certain size and stick the type to it but keep it out of the window frame.

    If you need to use lead-free solder be sure everything you want to solder is very clean, then smear solder flux on everything before you try to solder. It does help.
    Did you try bending the elements toward the coax to improve the SWR? It should act just like an inverted V.

    bamboo, balsa wood Yagi and fold it up with the copper tape stuck to it and away you go portable to the top of a hill and the antenna weighs nothing. Edit: Good idea using the tape, I used it for making ground planes for an antenna that went through a roof at the ridge. It worked very well, used four bits of tape as a ground plane stuck the the inside of the roof. Nice video. I have used a lot of things to get round someone living in a flat. It was the days of CB, so you can imaging how big the antennas were. We even used a curtain rail cut end insulated (plastic) in the middle (Brass plated) it worked well, though it was horizontal it still got him talking to his mates and it was spot on for DX. Brilliant idea using the tape.

    Back in the early 90's while working on the GM 'Backlight' program to design antennas on the rear window glass of GM cars we used copper tape to mock up antennas, worked really well! Fun fact: Detroit Greenfield Road area has broadcast signal strength as hi as 1,000,000 uV/meter, this was the test area for the program! GM radios performed poorly in that environment at the time! There was even cross-band suppression by 2 FM stations into the AM band at 590Khz where the GM radio goes silent even though there was a station there!

  • @mihaialdea

    Consider taping it on the outside. The UV filters and whatever coatings that glass have are a serius RF screen. My particular case is with a full size J-pole antenna inside the room, i can barely use the 70cm band. However on the outside I can hit the repeater with 2.5W with a 5cm rubber ducky.
    So the glass is killing the J-pole.

  • @svtelos4726
    @svtelos4726 3 роки тому +1

    The first thing that came to mind when I saw the width of the tape was. eddy current. Ordinary antenna and antenna wire have a high "fineness ratio" = small diameter compared to length and thus less area span-wise to 'wander' sideways. I would expect that it would be influenced a lot by nearby conductive objects like wires, or even the human body. Try waving your arm in the vicinity of the tape antenna and watch the SWR . just a guess.

    Hi Gil. Yes, lead free solder is something I always avoid - I tried it only once! The copper tape is very good. I have made a few antennas using this tape. Wrapping it round 4mm diameter glass fibre rod which is then covered with heatshrink makes an effective and robust whip type antenna. Also, I gave wrapped it around a plastic hula-hoop to make a very effective mag loop. Because of the RF skin effect, I suspect that this thin tape stuck to a plastic tube gives similar performance to a copper tube.

    Here is an idea, how about a J Pole antenna if you have a tall window. Another option is to find a large piece of thick Mylar sheet (might be available at an art supply store or a supplier for signage) and stick the copper to the Mylar sheet. You can roll it up and deploy when needed. There is another item that might still be available in the USA, it is called a Venttenna. It amounts to a piece of PVC pipe with what might be a J Pole stuck in it. It is designed to be mounted on top of an existing drain line vent on the roof of a building, yes its noticeable but my excuse is "I am venting the sewer gas a little further up so I don't smell it in my home". You could use the copper tape and Mylar antenna and glue it to the inside of a PVC pipe and attach it to a vent pipe. Its works great for repeater frequencies both U and V frequencies and if one lives in the hellacious area that is governed by an HOA (home owners association, usually a very corrupt self governing neighborhood zoning organization). Here in SV land if one is in good terms with all the residents of the condo buildings you live in you might be able to mount one on top of an existing vent on the roof, all that's left is to get the feed line down to your apartment.

    @Radio Prepper, Give the TS-100 or the KSGER T-12 solder stations a try. Fast heat/recovery on those, AND the T-12 has a few more watts than my Hakko 936 did. On the KSGER, make sure you groundbond the case, for safety.

    Next time, when soldering isn’t sticking (for surfaces like the copper band, not for delicate circuitry) try to use an aspirine as flux but avoid inhaling the fumes since are not healthy. Greetings from Germany!

    Cutting the tape along its length before removing the backing will yield strips of whatever width strikes your fancy.

    I've used the copper tape to make circuit boards on cardboard or wood surfaces. I've also used a strip of it at the edge of my electronics worktable, that was connected to a ground, so I could always ground myself while working with electronics. I like the idea of using the tape for an antenna on windows, and even paper, but instead of putting it on paper (and rolling it up, great idea) you could put it on a large piece of cardboard. The cardboard Yagi could then be easily turned if you're using it for direction finding... etc.

    A half wave of twinlead (free space length X 0.95 Velocity Factor) taped perpendicular to the antenna between antenna and coax should relieve some of the mechanical stress on the feed point. It will be easier to solder to and will also serve as a balun. KC5UES

    Flux paste and liquid flux is a game changer for soldering mate even with lead free which is terrible. Flux core solder does not always stick or flow due to oxides stopping the solder from sticking as the flux core burns off too quick.

      Only thing with lead solder you need to wear gloves and a respirator or have the fumes exhausted. I worked with lead solder for years and at 72 it seems to have affected all my joints!

      Lead fume is dangerous to the human body because its a heavy metal and toxic carcinogen. Use the tin solder with resin or buy resin filled tin. The lead only changed the working temperature!

    "Never use this stuff that I am using. It's total crap. Watch what crap it is as I use it." - Gil.
    I completely concur, by the way. I learned to solder online, and I'm not a natural at electronic stuff at all, so it was very hard and frustrating. Finally I posted for help in a ham forum, and the first thing they asked was, "You're not using lead-free solder, are you?" Of course I was; it's what they sell.
    Long story short, I followed their advice to get small-gauge lead Kester, and... miracle! I was the king of soldering! (I should have been; I'd been studying how for a year.)
    They should print a warning on the lead-free tube: "Warning: not really solder."
    Anyway, thanks for the excellent video. Very useful information.
