26mhz or so

lets add it up top whip >>> 70" cap hat >>> claims it added about 40" effective length cap hat extension >>> 12" main mast >>> 48" That makes it around 170" effective length while fully collapsed plus another 6" or so in connectors... that being said it's not quite...

Thank you! would you be interested in a tarheel cap hat that is only a few weeks old?

I am quite aware of this, but having less physical size on 80 and 40 WILL mean I take a hit there, and even a hit on 20 and 15 though to a lesser degree I tired 10m on the antenna and it did not work ou... but I knew this was likely before I even got started... so oh well

I could remove the cap hat... or the whip... either would get me 80-10 BUT then I take a hit on 80-15

ok with the antenna fully collapsed it tunes around 21MHz but I knew this would happen my hope was that the performance hit on 10m would be minimal... I also figured the 10m 2nd tap would be closer to 200-250 turns BTW the turns are rotations of the stepper motor in the antenna...

Right now I am running the Tarheel 200a with the 1 ft extension, the (tarheel) cap hat (20" spoked), and a 70" whip (I have ordered the Scorpion cap hat with 3 foot extension,.... it is quite a deal for only $100.00 shipped) The big problem I have ran into is that since the antenna is far...

I have the 857d and run it mobile a lot of the time, then when I take it inside I have it hooked up to an old computer running Windows XP Pro, 1.25GB of ram, 40Gb hard drive, and a 20" widescreen LCD the 857d bring a lot o the table for the price, with a rig like the 857d you can run 160, 80...

I am planning to weld right to the frame First plating a section of the unibody rail with 1/4 inch plate steel then welding the mount I build to that

Santa came early... now what do I build the frame mount out of? Will 1" round (ID) with a 1/4" wall welded to the frame work? (which I have laying around at the garage) or should I up it to 1.5" square, or even 2" square? (Which I will need to purchase)

the A99 is not the same thing, Antron 99, A99, 1/2 wave end fed antenna, about 16 or 17 feet tall Solarcon/Imax 2000, 5/8 wave around 23 feet tall

I am getting ready to install a 50 foot aluminum telescoping tower with a tilt base... it will have a 7 element 10 - 15 - 20 meter beam, and maybe a 6 meter and 2 meter beams as well as my 8 foot 2m/440 co linear I may also be setting it up as an 80m vertical, and maybe even a loaded 160...

I kinda thought so... well maybe I will try tuning the 6m halo that way too... it worked great on my 2m halos

Now I know that NORMALLY when we feed an HALO antenna we dump the coax shield to the center of the HALO and the coax center conductor goes to a gamma match that goes to one side or the other... HOWEVER when my friends and I built our 2m HALOs last year we fed them with out a gamma mach and...

hmmm... not impressed, I would rather hang an a wire in a tree... it would likely perform a little better too

Yeah it's just a piece of aluminum from an old set of crutches

yes actually I am exactly 1 miles as the crow flies from a place called 'Antenna Hill', otherwise known as "Television Place". There are SEVERAL TV stations, Studio to Transmitter Links and I have been told there are even a few radio stations... I can listen to a local TV station uplink on a...

well I think I know what is going on... I think something nearby is wacking out the antenna, reason I think this is that my SWR meter shows a 5:1 @ 51Mhz and the analyzer shows a 25:1 the meter also shows a 4.5:1 @ 54Mhz that being said adjusting the gamma does not seem to help much, if...

Another thing I had noticed is if I lay a wire on the loop going to the center conductor that the analyzer will start to show something on R
