With most of the discussions in this forum being pretty "high end" I am somewhat reluctant to even ask this.  But, I am wondering if a directional  antenna designed for consumer TV use would be a viable substitute for the $600 purpose made ones?


The Audiovox / RCA  ANT700  is available online for as little as $20.  Here is link to the product:

I have some of the Audio-Technica 3000 series units and thought a couple of these antennae might provide more robust connectivity than the 1/2 wave antennae I am using with the DA600 antenna distribution system.


Or are there internal capability / quality differences that would make these cheap antennae poor choices?

I have used (and continue to use) these for mics and iems, comparing them directly to the audio technica paddles, and they work equally well. MUCH more economical.

If you look closely at any manufacturer's LPDA, you will see that it is just a circuit board, painted black, with a BNC soldered to it (give or take certain refinements). I'm certainly going to take a closer look at those if I need antennas. I have also had very good results with these in a couple of installations:http://kaltmancreationsllc.com/pro-audio-wireless/wireless-microphone-antennas/

I had acouple of antennas like that, with SMA connectors, and they just didn't work as well as I expected.
Tossed them out.
The Shure had much better gain.

Which models have you used?
I got a chuckle reading about their "horn loaded" IEM antenna.

I've used the CP Array and the CP, with the latter used as both RX and TX (not at the same time!).

For convenience, here is a direct link to the printed circuit board antenna:

It seems like most of the purpose built Log Periodic antennae are "active" and need power.  Do the printed circuit boards in the link need power?  Not sure I understand the advantages / disadvantages of an active antenna.

The antenna you linked to , or any other "passive" antenna, doesn't need power to work.
The log periodic and helical is just like a "stick" antenna in that it can transmit or receive signals. but work better in one direction.
An "active" antenna, like the Shure UA874, has an amplifier that can make up for long cable length signal losses and does require power to work. It is a receive only device but the element is the same design as the Shure PA805.
The design of the antenna element has more to do with what application you use it for rather than if it is powered or not.

I just did an outdoor  tree lighting with choir and other activities on a closed downtown block.  I set the wireless rack with the DA600 antenna distribution unit and its 1/2 wave antennae about 50" high near the ceremony.  That all worked well for the choir and MC in that area.


Then some of the organizers suddenly wanted to do announcements  100 feet down the block and the wireless MC mic did not work so well for that.  I know this setup has the range to do this as I have done shows at that distance.  But I had good line of site from the receiver at FOH to the stage.  This time there were many bodies between the antennae and the MC.


So I am still thinking I need something to improve the reception.  It is not practical to raise the DA600 up to a high elevation.  So some sort of antenna on a pole is what I think I need. Some questions:


If I use  LP type antennae will I have too narrow of a reception coverage pattern to handle a choir at 90 degrees 20 feet away and a separate mic 270 degrees and 100 feet away?  That is 180 degrees of coverage is needed.  Or would I have to point the paddles to where they are needed?


The Audio Technica 3000 series is a diversity setup and so needs 2 antennae.  My understanding is that a diversity system is constantly checking which channel has the best reception and switches between them as needed. This is probably a dumb question but would I be likely to get good results with just 1 LP antenna hooked to the "A" channel?  I could elevate the antenna so it had a good line of site to the mic down the street.  Or would this really mess up the reception on a diversity unit.  I am not trying to cheap out, it is more about streamlining the setup.  These are often combat situations with lots of bad weather and awkward places for me to set up.
