V quad or delta quad is what I remember. Something like this: http://www.ebay.com/itm/Smallest-Beam-Antenna-MaCo-V-Quad-14X-Multiply-/130525843294#vi-content

Another cool one: http://gizmotchy.com/index.html

In answer to you question I see you have a couple options. Catch Larry on the air (or email) and bounce it off him. He's a great guy always willing to help you out, or just try it and experiment around a bit! Thats all the fun of it  Roll Eyes

My thoughts (no expert), is you might have to fight some interaction with the attic wiring etc.

73 good luck. Let us know how it turns out

Hi Bob,

Good question.  I don't know thewhole  answer, but it would seem to make sense..kinda like a wire log . Now how the pattern would be affected may be a different story.

I know you Bob, JUST DO IT and let us hear it on the air.   Roll Eyes Roll Eyes Roll Eyes

Hi Kuby,

Hope your doing okay up there.  I always put mine below the beam on the mast out of the rf plane. No biggie on pig tail length. I made mine from a 8 in piece of PVC to G3TXQ's data. Of course a Ferrite is better...but I have had good luck just following the instructions lol.  No real common mode to speak of.

If you looking to buy one http://www.hy-gain.com/Product.php?productid=BN-86 is pretty okay one packaged. I would stay away from the cheapos.

Email me direct or catch me on the air if you need any help.  PS are you helping the the special events this year?

My 2 cents...

I have owned one for a year and love it. All the locals have bought them and are very happy bang for the buck.  They aren't yeasus or kenwood but rival in performance. A little learning curve to program but no big deal.  Hot tip, use the software to program and you will be fine. Join the Yahoo group and read the FAQ there.

I carry mine daily and hit the repeaters no issues. A aftermarket antenna or mobile improves them as well. The factory antennas are soo soo but fine for local and small.

Did you update the display driver for win 7?  Did you check the bios and make sure the internal deiplay ports enabled?

11  eHam Forums / Elmers / RE: mounting 102 inch stainless steel whip on truck bedside on: April 10, 2013, 01:34:31 PM
My 2 cents  Grin

For a 102 in whip you really need the HD mount, better yet the mount with HD spring. The antenna naturally vibrates, esp the fiberglass ones hihi. This tends to loosen the mount bolt on longer antennas.  A 4 foot whip is usually fine with the thru hole mount.

Been there done that...

73 and have fun!

Check the exsising dual graphic and make sure theres not a win 7 driver avaiable for the exsisting on board chip set.

15  eHam Forums / Antennas and Towers and more / RE: Minimum sized rotor for Cushcraft MA5B on: February 28, 2013, 08:23:57 AM
A TR44 would be the best bet or a small yeasu like a G-450 IMO. A TV rotor will work fine, but the cheaper ones (like the home depo) last only a couple years. I would go with an AR22 but im very poor Smiley The 5B is a small very light antenna.

73 and enjoy  KD8GEH
