FM Indoor Dipole Stereo/HD Antenna with Fine Tuning

This simple design is the best indoor antenna available at any price.
This dipole is made for FM only. It is not made for television reception, only for FM.
It is the best value and is as good as any indoor antenna available anywhere at any price.
Now comes with higher-quality sturdier telescopic rods while not unbreakable are far less likely to bend or break.
To unleash the true reception power of this antenna mount it vertically as high as you can get it in your home on an outer wall.
It does have directional characteristics towards the flat side which helps handle multi-path and other issues that are characteristic of FM broadcast band reception.
You'll like the simple, sleek, modern design of the antenna.
This antenna comes with a 75ohm F connector that is standard on most modern tuners or receivers but you may choose another connector if needed including hard-to-find connectors at no additional cost.
Works great in any FM mode: HD, Stereo, mono, DAB, digital, SCA, or whatever your FM reception mode may be.
You will be very glad you chose this FM antenna! Check the feedback: hundreds of our antennas are in use around the world!
You will get your FM antenna quick as shipping is virtually instant.
This FM antenna is manufactured in the USA!
Manufactured for FM Reception
This is a brand new, unused professionally manufactured 1/2 wave dipole antenna with tunable rods that allow this antenna to be used where outside antennas are not allowed or are inconvenient. This antenna will provide as strong reception as any indoor antenna on the FM band. This antenna was produced for the FM band. With the rods fully extended they are tuned at 88 Mhz and you can then shorten them if you have a target frequency that is higher in the FM band. A length chart is provided so you can measure, with your tape measure or yard stick, the exact length each rod needs to be for a particular frequency.
In Use
This antenna is directional when used in the V configuration so use that to your advantage for your target station or orient it for best reception for the majority of your target stations. The rods are adjustable so you can adjust it exactly to the frequency of your goal station. Place the antenna as high as possible for best reception. Finally, use the tuning knob to fine-tune each station after you have done all the other steps. Generally, the common orientation for the radials in a V shape at 90 degrees with the flat side towards your target but using it vertically unlocks the true potential of this amazing performer and makes it non-directional; use the full vertical position if you can for the best results.
Flexible
This antenna can be used near the stereo or run a longer cable and put it near a window for best reception. You can use it in a portable setting or even mount it in the attic as it will out-perform any other omnidirectional you can place in the atttic. The only limitation would be that it should not permanently be set up outside, but it wouldn't hurt it to use it outside on the patio or take to a park in any weather just don't leave it outside full time.
PLEASE NOTE
While this antenna is made for FM and the functionality is amazing, the radials are constructed of telescopic rods that are made of chrome-plated brass. They will break so you need to be careful with them. Handle them near the base when manipulating and it is best to find the best angle and orientation and leave it there. Obviously, this is not a particularly positive thing to point out about the antenna but you need to know you are not getting an unbreakable antenna by any means, in fact, unlike most of our antennas we sell, it will break if mis-handled.

It is a dipole, and so has very little gain, it is directional, but once set in position can only work well, posted on November 8, 2009 at 11:45:09

for THAT single direction, and that station too - very likely.

This type is more commonly known as 'rabbit ears', and yes it is capable of being reset - for each of the direction + transmitter combos you need/want to receive - the results also still depend on luck - all such small indoor antennas do.

? The wavelength of a 100Mhz FM station is app. 3 metres or 11 feet. Yes, it is possible to get good results with small indoor antennas, and that's luck / being close. And, FM sound quality just does depend - heavily - on a directional antenna.

IE - If you want to optimise (?) the results for each transmitter (or a site with several transmitters) it will be necessary to learn several different set-ups: for each telescoping rod's length and orientation to the other, orientation of the base North/S/E and West, and the switch setting.

But at each set up - it's pick-up pattern will still be quite narrow - IE 40 out of 360 degrees - or a whole LOT less. Thus, when you move your own body(s) around break-up can occur. And, homes are full of Radio Frequency Interference (RFI) sources these days, to boot, which can easily overload many solid-state (SS) tuner's radio frequency (RF) front-ends.

It is your own reception conditions that are the context for whether this item is any good - for those conditions! Asking us here - without giving that context to us - can only elicit general principles.

How to know, whether you do know enough!? Try reading my recent 'getting started' post . Viz. What are your desired stations? where are their transmitters? how far away? mountains and hills, tower blocks, etc, etc.?

Do you really have to have an indoor antenna, do you have a loft / attic or two?

Now for some more comments about the specific antenna and the advertising text, and the company's FM range.

"This simple design is the best indoor antenna available at any price." ?

I doubt if the design was driven by the seller, because VHF-only rabbit ears, with/without a 'tuning' switch, have been around since the 1960's. ;-)!

IME rabbit ears - with a switch or without - are better than almost all other indoor VHF-FM/TV antennas, including all the powered ones, because they are an adjustable dipole!

So, I just might agree, but only if we are talking about items for sale - from shops or mail-order. And with 'indoor types' not being ideal as well.

AND if most of the desired transmitters were at one or at most two sites.

I don't think I'd want to try to remember more than two set-ups, what about you? Your SO is going hate it (and YOU) if she has a station she loves that needs another set-up of the rods and switch and base, esp. if she only uses it every now and then, and forgets.

But, if we count a DIY rhombic as 'available' and also directional, no it isn't the best, and by a very big margin. Even if you'd need to DIY more than one rhombic.

No commercial indoor FM antenna is a good option. Not big enough / nor enough gain / nor sufficiently directional.

Not one of this companies FM antennas is suitable for FM DX-ing. DX-ing for FM is trying to receive stations hundreds of miles away. So, why does he use DX in the company name?

As I have posted before, it all really comes down to how valuable FM can be, to you, where you live! And as a consequence, how much personal input, research, thinking and physical work you are willing to put in, to max up the results to meet that value, for your listening!
