FM Antenna

Recommended Posts

I finally lashed out on a Sansui TU-X1 tuner. Gotta love something worth more now than when it was new over 35 years ago, but they have a great reputation and I do desperately want to be able to listen to live concerts when possible...sort of make it a date with my wife, put the kids to bed and retreat to the music room to listen to Mahler down at QPAC or the BBC proms at Royal Albert Hall.

So I call a local antenna mob about installing something on the roof to point at the Bunya Mountains so my ancient, overpriced, oversized black box of Japanese beauty can help me enjoy quality time with my lovely wife that I no longer have to woo but want to anyway. But there is a spanner in my plan...the antenna guy has never done an FM installation and I don't really know enough about what I need to be sure someone like that gives me the right tool for the task.

Who am I gonna call? Where do I find info on the antenna I need in my specific situation? What can I read? All help appreciated.

Cheers,

Anthony

cant help you, but I have a bucket of popcorn and waiting to see how you go.

 

I've been trying to get Melbourne FM here for years. On a good night I can almost get it in my car but not sure if the signal is only here sometimes. Maybe those nights the signal is bouncing, kinda like skip talking in the old CB radio days.

 

Maybe @@catman knows something?

I Anthony,

 

I just went to my local tip and bought for a couple of dollars and old analogue TV aerial.  I put it on my FM aerial pole and connected it to the amp box at the top.  At the other end with a splitter I took a lead to the FM source.  Works fine.

Best FM antenna

You can make it yourself

Right, so I hit googl to find you some links .... and come up with nothing.   That's pretty bad  :/

 

 

Anyways....   You need a "band 2" VHF antenna.    Polarisation (horisontal vs vertical) is different between stations in Oz, so if you are marginal with your reception, you may need to experiment with how you mount it.

I live only half an hour from you.  With my set up I can get Ballarat FM 105.5 fine.  If you are after commercial FM from Melbourne you maybe expecting too much as the FM signal does not travel as far as AM.  Just tune in through the respective station's web site

Hi Anthony

Cant help but laugh - I had a Linn Kudos tuner - lovely. Worked like a charm in Alice Springs with and internal antenna. Move to Grafton, no luck. Using it in my office there is no way I can install an external antenna. So I go to the local radio installation business. They sold me an antenna similar to what you put on cars and boats - still not luck.

So I sold the tuner and now listen to radio over the internet - sad.

Anyway @ Asissi is correct - that will work. 

Good luck :)

You might be right there John, all my attempts have been futile. UHF and VHF aerials, and I still cant get the signal. Cant make silk purse from sows ear, but cant make sows ear from nothing.

G'day all, if you are not too far from your local FM transmitters you can build this simple 2 element yagi which works very well for its simple design and compact design.  I have built several of these with very good results and our 'local' FM  transmitters are more than 70 miles away.  Regards, Felix (vk4fuq).

Hi Anthony,

 

I bought one of these antennas about six years ago http://www.academytv.com.au/products/ATVFM3--%28FM-Radio-ONLY%29..html

I live in a poor reception area but this FM directional antenna solved the problem!

They also have a bigger model antenna than the above one if need be. You'll need a (from memory) 75 to 300 ohm balun as well (plus some coax 75 ohm cable as well). Your 'antenna guy' should be able to figure out the rest, one would hope... good luck with it.

When i looked into an Ariel for my NAT101 tuner i was told the best one to get was a Ron Smith galaxy, it may suit your needs too. Best of luck.

And use good quality low-loss RG6 quad-shield coax from the antenna to the Tuner.  

A lot of signal can be lost in the cable run.

Yes.  As to whether you need one like catman posted through to one of the large galaxie antenna ... You antenna guy should be able to measure the signal strength where you are and advise on gain required.

Thanks for your input guys.

 

A bit more information.  FM transmitters for the two stations I am interested in are almost exactly 85km away on top of Mt Mowbullan.  I am located in Toowoomba which is quite an elevated town, about 700m, but the house is in a valley with extensive trees in the direct path to the tower.  Our television signal, which also comes from Mt Mowbullan, suffers because of these trees particularly in windy and wet weather.  Saying that, I can sit in the driveway in my ute with its standard omnidirectional antenna and get FM perfectly well for both stations of interest.

 

I have been reading about the TU-X1 tuners and it seems as though it is possible to flood the 75ohm input with signal if the antenna used has too much gain  and things sound worse.  People in this situation fit an inline attenuator to drop the signal strength of the signal they have just used a high gain antenna to amplify so understandably I am hoping to avoid this situation by fitting a directional antenna with the right amount of gain.  The antenna will need to be directional because being on top of the range and within reach of Brisbane there can be quite a bit of crosstalk between Bris Vegas stations and other stations to the west.  Luckily all the stations that I am interested in beam from the same mountain, so a directional antennae should work well when pointed away from Brisbane.

 

So, I think some kind of yagi is going to be the right result.  I might choose something mid-level for gain, say 5dB and see how that goes.

Yep, I have run the quad shield already into the new music room.
