I took a can of compressed air and was able to dry it out. After it was dried, it tuned fine. Next rain, same thing, stopped tuning! Dried it out again and started thinking, this thing is going to corrode. NEXT DAY, (yes it rains quite a bit in the midwest at times) it stopped tuning AGAIN.

If you see a cloud in the sky,,,,,,,,,, TAKE COVER!!!!!!!

THEN TAKE THE ANTENNA OFF AND WRAP IT IN A BLANKET AND PLASTIC BAG!

CODDLE IT TILL THE RAIN STOPS. WIPE THE CAR DRY AND THE ANTENNA MOUNT AND WAIT FOR A FEW HOURS TILL THE ROAD DRIES AND YOU WILL BE JUST FINE =)

When it gets wet, its done.

If someone says the WORD rain, this thing stops working!

It is a mobile antenna, you can't expect it to handle the outdoors can you?

How can a mobile antenna be so prone to failure when used outside as a mobile?

I have a High Sierra Sidekick and a Tarheel II, both of them blow this ATAS 120A away,,,,,, RAIN, SLEET, or SNOW!

My kid now uses the ATAS as a throw toy for the Chocolate Lab.

I really do not want to open the thing and make a mess.

Question is, if I transmit into the load, should the SWR read a perfect match of 1:1 ratio. It should not reflect power back to the transmitter. Is this correct?

I would assume the impedance of this load is 50ohms, but could be wrong. It was used at a now decomissioned AT&T telephone microwave hop so it could be 75ohm or some other strangeness. ]]> Amateur Radio Antennas towerdog http://www.worldwidedx.com/amateur-radio-antennas/37166-dummy-load-question.html http://www.worldwidedx.com/amateur-radio-antennas/37162-military-random-wire-high-frequency-lo-band-backpack-antenna.html Wed, 18 Nov 2009 05:22:06 GMT I saw a photograph somewhere of a soldier in Afganistan with what appeared to be just a random wire snaked through the molle webbing of his LBV.

It looked like it had some sort of balun too and then his radio on his back.

Is anyone familar with this system. I would like to build something similar on my backpack for 6m/10m and most of all, yeah, CB.

I do not know much about random wire, other than of course its really poor radiation and something about you want the feedline to not be of certain lengths depending on factors.

This setup must work as well or better as a loaded 1/4 or 1/8 wave if the military uses it.

Well, any useful knowledge be appreciated. ]]> Amateur Radio Antennas towerdog http://www.worldwidedx.com/amateur-radio-antennas/37162-military-random-wire-high-frequency-lo-band-backpack-antenna.html http://www.worldwidedx.com/amateur-radio-antennas/37138-x-counterpoise.html Mon, 16 Nov 2009 21:15:13 GMT Every commercially built antenna I've had on the suburban typically gives me "x" between 6 and 11, with "r" somewhere between 45 and 55 and SWR of 1.1 to 1.3.

In the process of winding up my first homebrew antenna this weekend for the mobile, and after a little too much adjustment (= cutting wire :oops:), I stumbled across a very good fit on 28.5mhz. x=0, r=50, swr=1.0... I've never, ever seen that kind of match before and it got me thinking about the vehichle more and the antenna less.

If I'm able to achieve an x of 0 in the shorter wavelength but not on the target frequency, could it be an indication of inadequate counterpoise? At this point I've done no bonding whatsoever and have no reservation about experimenting with it. Just wanted to see if that train of though made sense... ]]> Amateur Radio Antennas ROC1 http://www.worldwidedx.com/amateur-radio-antennas/37138-x-counterpoise.html http://www.worldwidedx.com/amateur-radio-antennas/36998-high-resistance-citizens-band-radio-2m-mobile-antennas.html Sat, 07 Nov 2009 04:30:19 GMT I've got a problem that I can't figure out. I have high resistance, by about 20 ohms, on both my CB and 2M mobile antennas. Both are mounted on 3/8x24 stake pocket mounts on my pickup. There are no shorts in the feedline, no shorts on the mounts and they are grounded to the frame with grounding strap. I've also grounded the bed to the frame with grounding strap.

Any recommendations? ]]> Amateur Radio Antennas AndrewGS http://www.worldwidedx.com/amateur-radio-antennas/36998-high-resistance-citizens-band-radio-2m-mobile-antennas.html http://www.worldwidedx.com/amateur-radio-antennas/36935-sigma-gp-430-a.html Tue, 03 Nov 2009 10:01:05 GMT Hi,

Is there anyone who has experience with the sigma gp-430 ?
i could not find any reviews about it.

Think that may be like a 1/8th wave... Glad the radio didn`t blow

I was on 10 meters last night and forgot to switch over to the wire.

They don`t call me dimwit for nuting.

BTW, makes a great short wave antenna also ]]> Amateur Radio Antennas Dealer http://www.worldwidedx.com/amateur-radio-antennas/36896-dare-i-tell-you.html http://www.worldwidedx.com/amateur-radio-antennas/36851-full-wave-10m-antenna-will-work.html Thu, 29 Oct 2009 17:38:55 GMT ok, any ideas whether this will work or not?

I have two 9' fiberglass poles that have mounts (normally used as flag maker polls on off road trucks).

If I start from the base using winding coil wire (unsure what gage to use??) and run it straight up the side to the end of the poll. Than turn around and run it back down to the base. (now I'm up to 1/2 wave?) now repeat for the two remaining "sides" or quarters of the poll. Have I now reaches full wave? I would than finish it in the standard way, leaving a way to tune it. Does this sound like it has possibility?

Also, if one would work at full wave, would constructing two polls of this sort and putting them in phase be better or would that not work as it is already at full wave?

Thoughts, ideas???

Why would anyone buy an antenna for two or four times as much money as it would cost them just to make it?
That's not a 'trick' question, it's for 'real'. Lets also qualify it to some fairly simple types of antennas, not the 'elaborate' ones. For instance, dipoles or 1/4 wave verticals.
I've seen a pretty fair amount of people/companies selling dipole antennas. They have all been at least three times what you could make them for with just a little bit of research, digging through the 'junk box', and maybe 20 minutes worth of time (change that 20 minutes to an hour just for the h@## of it).
I have to admit that my 'junk box' doesn't have anything in it that would stand up straight for a vertical antenna without some 'help'. I might 'splurge' a bit for one'a those.
I also have to say that I don't much care what an antenna 'looks like' as long as it works. Looking 'nice' is nice, but it isn't exactly a biggy, you know?
So why would anyone do that buying instead of building?

I finally got my rig and got an excellent deal in the process. I am the proud owner of a Yaesu FT-897D w/FP-30 internal PS, LDG AT-897, and 5 vertical antenna's for 40,20,17,15, and 10 m. All for $1050.00. Now that's the good news. The bad news is I've been scanning the 40 meter band for about 3 hours now and I can barely hear anyone, except for one and I found out by his callsign that he is the next town over. I have yet to have anyone answer my call. My feeling is that my transmit is not meeting the range of my recieve, by a longshot. I'm pretty sure my issue is the fact that I live in an apartment and I put the 40 meter antenna out my one window. The possible problem is that the antenna doesn't clear the surrounding 4 walls. I live on the 3rd floor, but the top of the building extends further up from my floor. I don't have access to the roof so I can't move the antenna up there. Does anyone have any ideas? Are my assumptions correct or is it something else? Would putting an antenna "in" my apartment give me a better outcome?

Thanks in advance.
