The Switronix Recon and some modified Wevis have removable sma antenna. Does anyone know if a 2.4GHZ antenna works on 5.8GHZ system? Considering its nearly a multiple in frequency I thought they might.

Can anyone recommend a flat panel antenna that takes 4 sma antenna wires? I have seen people using these before.

Can anyone otherwise recommend any cool antenna to play with?

You want antennas that are specifically for 5.8ghz not 2.4

These antennas will add gain for 2.4 and 5ghz, I've used them for wireless video applications.

So Will, you're saying that if the antennas you linked were ordered with the SMA attatchments they would work for the Recon? The biggest complaint I've heard about it is that the stock antennas are flimsy and fragile.

Switronix, while great for the price, is very very very cheaply made. The antennas are not really the problem. It's what they screw onto that spins and just gives an incredibly clunky feel to the unit.

They really should address this.

No doubt its manufacturing is a concern. Thats why I want to send SMA cables to an Antenna array and keep the whole thing far safer.

If someone let me open up their Recon, I'd be happy to look at the SMA bulkhead connectors and think about easy ways to secure them so they don't "spin". My first thought is epoxy: two dabs on either side of the bottom of the connector to secure the bulkhead to the device. Moreso, maybe someone makes a solid plate to go over the connectors, creating a mechanical stabilizer for all of the plugs?

I liked those antennas because they're not the wobbly "fingers" style. You set them where you want them, and they stay there.

Here's the inside of a Recon Ultra. Posted Image

Thomas, I'm looking at panel antenna right now and, while I'm not finding an antenna that takes 4 connectors, I feel it's possible to create an array out of some of the ones I'm finding. I'll keep digging.

Yeah, I've seen panels with 5 antennas all integrated but at different angles. I've looked high and low but I can't find where to buy them.

Small panels would be cool. Put them on a T bar and point them and twist them differently.

Thomas: I'd be willing to bet that those are built custom. I think you need some high-gain flat panel antennas (they are unidirectional, so the gain is significantly higher than omni antennas) build into, like you said, a T-bar. Wire them all out into a 4-5 cable "bundle, and run the bundle over to the inputs.

Well, they did the same low-cost solution to keeping the RP-SMA connectors from spinning: a bit of glue on the inside. If those wear out or crack (due to someone screwing down the antennas way too hard, which I'm sure happens daily), then it'll just spin inside the case until eventually it pulls the connector off the board.

http://www.moonblink.../cat_515585.cfm Just as an example.

Look for RP-SMA connectors on those antennas, or make the cables to go from those antennas to the Recon, and you're in good shape. Of course, you're just increasing the sensitivity on the receiver end. You still have the same antennas and amount of broadcast amplitude on the transmitter end.

The array's are built custom, but the panel antennas are most likely these:

Laird TriBand 5ghz Panel Antenna

I'm almost 100% certain these are the antennas that HP Video uses.

Those are really good links William and Dean! Not only do these little flat panels need to bee pointing in different directions but they also need to be rotated differently up to 90 degrees for different polarizations. (some straight, some 45 and some 90).

So it will be interesting to find some where the bracket easily allows this.

Dean, I am not sure that is the one HP use. 16 degrees or 8 degrees seem like a very small pattern. I would expect to see panels with around 70 degree to 100 degree patterns. 16 or 8 degree seem like direct links to me but I defer to someone with better knowledge in these matters.

The color and design on the front of the panels look identical:

I agree it is an identical casing. I wonder if its a case that all the chinese manufacturers use the same casings for their products or if it is the same Panel.
