daveb,

Yes it can. It covers 11 meters quite well.

Got my SKYLAB today, it took about 20 min to put it together. The instruction sheet does not tell you very much, but if you put antennas together before it will go together easy enough. This weekend it will be 50 feet in the air! Depending on the weather.

You guys should find the Skylab to be very broadbanded. You will not have to adjust this one to work 11 meters.

Yes, the Skylab is a 1/4 wave antenna.

If it bothers you that the SD'r has a quarter wave radiator, then consider it a modified 1/2 wave vertical dipole. It responds just like a 1/2 wave dipole. You will not find a better matching antenna on the market if you get it 30' high or more.

To those that really care and will notice, the SD'r will not show the gain, TX/RX, you may get with other antennas, but you will probably never loose a contact due to this fact. The SD'r has great ears and is very quite with regard to ground noises.

There are a lot of considerations to be made with you question. However, I would have to say no.

I understand this antenna is Illegal to use on the 11 meter band, can you give me feedback on this?

not at all mccool...perfectly legal for any band you can make it work on. I know people that run them on 10 and 11 meters and I believe Bruce has one cut for 6 meters

The U.S. has rules that say a commercially available CB antenna must protect the installer from electrical shock up to 14,500 volts. That means nothing except to the CB antenna makers. Since the T-233 is a '10 meter' antenna, it does not fall under this rule. The good news is, the T-233 works wonderfully on CB too.

So what you are saying tech 833 is that it is Illegal to sell this antenna for CB use since it will not protect the user from a 14,500 volt shock. But if I put one up and use it on the 11 meter band will I be subject to a fine?

Bruce is it true they can be cut down and used for 2 meters too? I know a guy that used to have one( he was using it for CB before he went ham) that he wanted to cut for use on 2 meters but i havent heard anything out of him in over 4 years. Hes an old CB friend that went ham back in the mid 1990s..

i would think so i cut one for 52 mhz and it works great! INFACT you could cut ont for 52 and with a bit of skill use the leftovers with a added bracket and connector build a 2 meter one from the scrap!

I bought a t-233 about 6 months ago and have loved it's performance on 10 and 11 meter bands. Recently I had to take it down to reshingle my garage roof and in the process it fell. Didn't seem to do much, just bent the top aerial a bit and 2 of the downward ones. When I put it back up though, I have extremely high SWR now and can't seem to get it back down. Before the fall I had a 1.1-1 and now I have over a 3! Any idea's what might have happened and can I fix it?

Depends. How much power are you using? What's the limitation on the antenna?

Or, it's stress fractures from high wind forces.

Hey turtle if you can't get one from the place you bought the antenna, then just put it up without. I never put those on the SD's that I have installed and they work find. That is just not enough material up there to make a difference and if it is supposed to act like a top hat inductor, it needs to be at the top.

Go for it.

i had bought the skylab assembeled it in 20mins put it up in the air about 85ft.The antenna had a swr of 1.1, transmit and recieve was good, but i live right by the ocean and the wind tore the antenna to pieces within a year. I bought a maco 5000 and works better and has been up at 100ft with no problems it takes more time to set up and tune but its worth it

I had a Starduster up in the late 70's.
It withstood about 3-4 years before winter
winds destroyed it. I have another one
down in my cellar in my old antenna collection.

Hello, I have used a starduster for 4 years now at 45 feet. I can talk to most skip I hear and run aroung 300 watts through with mini coax. I primarily talk on 38lsb here in North Central Indiana and would like to see if the I-max 2000 is worth getting. Would I notice much My SWR is 1.1 across 11 meters. Thanks for the great info. AK3383

AK3383- I do suggest one thing: The antenna
and coax are the most important part of
your system. Put some good low-loss coax on your antenna system.
I also suggest you make a post of your own with
your Starduster/Imax 2000 question.
