Yagi Frankentenna question.

[Sev]

Hate to ask what is probably a redundant question. However I didnt find an answer in my searches.

I have seen some discussion where have bought 2 91X style antenna's and added the middle of the second to the first for extra gain.

So I currently have 2 radios shack antenna's. VU-190 XR and a VU-120 XR.

My thought was to cannibalize the 120 and add its yagi components to the 190.
I could sleeve the yagi component by using the center connector.
Then fabricate sleeves to increase the size of the corner reflector.

It would be a net gain of 33 inches of antenna and 24 inches of reflector.
On the reflector I would have to switch out two of the elements on each portion of the reflector to maintain the position pattern found on the 190.

Would this be a go or no go?

Thanks guys.

My experience with random guesses is that it rarely gives anything other than random results. Most antennas including the products that Radio Shack used to sell are engineered by people who know the science and math.

Odds are you will ruin two good antennas and have an contraption that looks big but performs like a coat hanger.

Sorry to be so pessimistic, but that's how I see it.

LOL.
That is what I wanted to know.
Extrapolating out proportionally doesnt always work.
I thought perhaps somebody had tried it. It would make a yagi 76 inches in length with matching components.

The 120 is not in the best shape. I did see where one guy did cut the yagi off and mount that to good effect.
