61  eHam Forums / Antennas and Towers and more / Loop lovers only! on: April 24, 2007, 09:58:04 AM
 Well, ok anyone can read this but my question is directed at those who have a horizontal loop or have experience  with them.
        I erected my first loop about 6 years ago it started as full wave for 80 meters. Over time it has gotten bigger, smaller, higher etc. Now  its  about 235 feet long , more or less square and up about 50 feet fed with 300 ohm line. It works and always had worked better than any bazooka, double bazooka, dipole, dipole as a V, L, H, sloping, OCF, G5RV, Sturbas, bobtails, windoms, randoms, fans, wire beams, ground planes, verticals, and who knows what else.
      My question is simple, what other antennas do you now and have and how are they better than your loop?

 I would take a piece of plastic, lexan, nylon etc. even PVC pipe section will work , anything non conductive. Drill enough holes to secure your wire segments  as will as two to accommodate a bolt . Run the bolt through the plastic and attach all the appropriate elements and half the feed line. Repeat for the other half. There you have  it no soldering needed. You may seal the connections if you wish but i would guess you will be experimenting and changing things long before corrosion sets in.

Just get it close. The first wind overnight will knock it out of whack anyway.

From the online manual first hit upon googling.....


"MemoryBackup
Normally, a lithium battery inside the transceiver
retains all settings and memories while
power is off or disconnected. If the transceiver
looses its memories (but still operates properly),
this battery should be replaced.
The front panel must be removed to gain
access to the battery, which is on the inside of
the front panel, just behind the memory box on
the display. It should be replaced only be an
Yaesu-authorized technician to ensure that it is
installed properly."

"Q: What the heck is a swamp cooler and how does it work-Jack W., Washington D.C.

A: A swamp cooler (more formally called an evaporative cooler) is essentially a large box-like frame containing a big fan and walled in by water-wetted pads, usually made of cedar shavings or cellulose. The fan whooshes the hot outside air through the dripping pads (which are continually soaked by a water pump), cooling the air by about 20 ºF as the air evaporates water molecules from the pads. The fan then blows the water-cooled air through the house and out a deliberate vent."


I just had to look this up

If thats what you got use it, this will be the first of many antennas you will build. I have used bell wire, old extension cords, hook up wire, braided cable, slinkys, if its metal it will work!.

 NOW...... that I look at the item, I was incorrect, I leapt before I looked. SAV is correct.

 I guess you should have asked for "sloping dipole" info.   Generally build the standard dipole for your band of interest and then attach one end high as you can and the other wherever you can. Important to run the feedline at 90 degrees to the antenna.
69  eHam Forums / Station Building / Is this a good deal..?? TS-820S or TS-50..?? on: March 07, 2007, 12:42:57 PM
   RE the 820:  She writes  "He turned it on the other day when he took the photo and it was working.. "


     How was it working when he took the photos without any power cord hooked up ?  In any event will they provide the power cord? This radio is  made to run on 110 vac and a special connector is needed to hook the power wire to the rig. Which is not pictured. It also looks a bit scuffed up, all in all though if it "works" and they give you the cord and a mic I would say take a hands on look at it.

 I can tell you that Yaesu's have been known to loose their memories when power interruptions are encountered, maybe not a big deal unless you have done a lot of programming of memories but something to be aware of.

probigation ?      Sounds like a word that a prominent Texan might use...

75  eHam Forums / Antennas and Towers and more / Your Opinion About The Omni Loop on: February 26, 2007, 09:52:28 AM
 130 dollars is a lot to spend when you could make your own, hope it is very well made. That aside, loops are superior. I fully agree with TDG

    "I have tried everything that can fit on a 100 by 60 ft city lot....and nothing beats a loop, either a vertical or horizontal one."

     I too have similar experience.
