Antenna For Ramsey 100B

[eagle5 0]

I purchased a Ramsey 100B without the stock whip antenna. Besides the stock antenna, has anyone used a different one.  I'd like to find one that I can put in the attic or possibly on the roof.  A link or model # would be appreciated.

Thanks

I use a J pole and attach it to the top of my mega tree above the star on a 10 section of light conduct, here is a link to show you how to build and cut.

My head hurts now.  I might have to purchase this one, don't trust myself to make one. Thanks

Here is one that is a little easier to make.

I think I understyou and this one better, except for tuning it.  Can you school me a bit without too much confusion?

Let's do the math...

 

What frequency are you planning on using?

97.3

Here's a thread from awhile back that many people used to make their own antenna.

Use one of the calculators out there.  I think I used this one:

the diagram with the dimensions drawn out for you make it really simple.

 

With my JPole mounted on the eave of the second story of the house, my Ramsey can go two miles at just a little under full power  (so, I keep it turned down a little now)

So the formula is length=2808/Frequency, so:

 

2808/97.3 = 28.86"

 

The radials are 5% larger, so:

28.86*1.05 = 30.30"

 

As your tape measure probably only goes down to 1/16", round these off to

28.875 - 28 7/8

30.3125 - 30 5/16

 

Note the top of page three.  He adjusts his antenna to the middle of the two frequencies that he uses.  You can also translate that as you don't have to be very precise.
