Used Cessna antenna as a base antenna??

(1/4) > >>

NelsonC:
Hi guys, I'm working on my PPL and have just started getting into scanning. I recently was given a Maycom AR-108 handheld scanner. I've also purchased a Watson W881 handset antenna and a Workman magnet antenna for the car.

Now I'm on a mission to get this thing setup at home. I started to cut the pieces for a J-Pole (I live in Brampton and want to pick up 121.3 as well as much atc from Toronto/Pearson as possible).

It occurred to me that maybe I could just get a used (new is like $400) antenna off of a Cessna.....??? I think that these are grounded on the chassis of the Cessna but I could mount it on a metal plate and then ground that plate (run a wire to the cold water line outside).

Has anyone tried/heard of this??? Am I better off with the J-Pole???

thanks,
Nelson

I personally think you would be better off with a j-pole specifically cut to that frequency.  A jpole should be much longer than a C172 antenna.  I'm still building mine, I'll post to let you know how well it works.

NelsonC:
Hmm...I keep thinking that maybe the Cessna would be better because it would be built to aviation specs....but maybe your right :|

I have actually cut the pieces an assembled it dry (not sodered) just to try out but it kind of...sucks. After hearing all the good things about J-poles I was disappointed but maybe I have to actually fine tune the lengths and soder everything together.

I was hoping that someone had tried this before because I would prefer a more stealth/smaller antenna like the Cessna (I already have 3 small dishes and one 10 foot dish on the roof!).


PS. I actually already hear alot in my room (second floor) with just a long piece of wire touching the original antenna. I hung the wire virticaly from the top of my window blinds and the tip touches the top of the handheld antenna. Some come in ok but most, including the ones I really want have alot of static.

Maybe the quality of the antenna is better in the Cessna antenna. I couldn't try it, but maybe if you get it really high, it would suit you well. But otherwise I would go with a J-Pole (price & a trusted method). Then again, I've never seen an aircraft antenna up close and don't really know what they're capable of.

I was disappointed with the quality I was getting out of my J-Pole by KB9VBR (http://www.kb9vbr.com/products.htm), but with some adjusting and fine tuning it now works perfectly.

You can tune the J-pole to 125 MHz which will likely bring you good/great results (tuned to air band).  I personally have no clue what you'd get with the Cessna antenna because I've never tried it.

Also keep in mind that the Cessna antennas are built and installed to certain specifications to make receiving and transmitting at altitude possible.  It may not work so well when you're far away from the field and aren't too high above the transmitter.

I'd prefer the J-pole simply because it is a LOT cheaper and many people (including myself) have had great success with it.

Jason
