Has anyone used this antenna setup from Array Solutions? 12' Whip antenna w/AH4 or similar antenna? Would it make much difference from 8' whip antenna? Just curious...Thanks N0TJO

The individual parts are available from the prime sources, but it is sort of nice to have just one PO as it were.

Length matters! In fact, at 12 feet the AS antenna is double the radiation resistance than just the 8 foot whip alone. Installed correctly, and driven with an AH-4 or other coupler, it would make a fairly good mobile. It just depends on how much you're willing to put into the installation.

Yes you will see a difference going from 8ft to 12ft, especially with the AH4 tuner.  

The array solution's whip and more so with the spring/mount price seems high, but I have not actually seen the actual product.


I have run a 8ft and 12ft whip with both the AH4 and a SGC tuner and with the ah4 the bigger whip for 80m is a must, a big help on 40m. Below 40 there is a little  difference between the two legnths but you can live with 8ft.

If cost is a factor a 8ft CB  whip with a DX engineering mobile mast  can extend your whip length by 2,3,4,5,6ft and is quite a bit less than the array solutions but machanicly might not be as strong as a single whip.

On Alan's advice I put a 3' mast under my 102" whip fed with an SGC-237.

It's too tall and wobbly to run without being tied down as the Hustler ball and spring isn't up to it, but it made a big difference for 40m use.  Now I have a useful signal.

With the mast in place I can't tune 6m though, so I remove it for that.

80m is loadable even with the 102" whip, but the radiation efficiency is almost zero so I get nowhere with it.  For 80m I'm convinced you need a tuned resonant antenna or game over.  For that matter even at that an amp would be a good idea as well.
