I would say the Remtronix REM-810S. Made specifically to work with the SDS100 without the need of an adapter. If it's anything like the BNC version it should be a good one.
For 800 MHz I would go with the new "Available soon!" Remtronix antennas designed for the SDS100. The REM-810S does not have the O ring while the REM-820S has the O ring: https://remtronix.com/antennas/

tinocup - try the Radio Shack center loaded telescoping HAM antenna, its 6" closed and 26" fully open, you can Learn to tune it so that its Resonant on the frequency you want. its good for 25 MHz - 1300 mhz. Excellent ALL BAND All Mode reception.
Note that it really depends on what you are wanting to receive. 800 MHZ? VHF? UHF? All of them? Also, are you trying to pull in really weak signals or primarily local transmissions (in which case, pretty much anything works OK). All antennas work to some degree across all bands, but are designed to have peak performance in specific bands.
700-900

Thanks for the information update regarding the new Remtronix REM-810S and REM-820S antennas designed for the SDS100. I checked with Universal Radio today (11-14-2018) and they said that they will be carrying them but they do not have them in their system as of yet. Pricing information was also not yet available.
The REM-820S has an O ring to keep water out. Has anybody tried the one I posted from ebay. 6 vs 11 DB gain?
FYI you can now order the new Remtronix REM-820S 800 MHz antenna with the O ring for the SDS100 from Universal Radio. The price is $22.95 (plus $6.95 flat rate shipping on orders up to $50.00) and the Universal Radio Order # is 6269: https://www.universal-radio.com/catalog/scanners/6100.html
11db gain? :roll: More like 11db pain when you poke your eye out!
I can see Uniden getting a lot of repair business from this antenna to replace broken SMA connectors.

Looks like the ebay antenna are made of three antennas connected on top of each other. That makes it extreamly sensitive to the angle it has, the more gain in an omni antenna the more crucial it becomes, and must be absolutly vertical to perform better than the stock antenna. Tilt it just a little bit and it will be worse than stock.

I've found the Radioshack 800Mhz antenna with BNC to be best. (Similar to Remtronix)
I use the SMA to BNC connector that came with it the SDS100. I placed 7 stainless steel washers 3/8in in between the scanner and the BNC. Fits perfectly around the BNC to SMA connector. Connect the BNC side to the antenna, then ad the 7 washers, then twist the SMA on to the SDS100. The washers act as a external heat sink. Works great! Radio feels much cooler! Washers are snug. Haven't noticed any signal loss being the washers are sandwiched between the radio and antenna.

Universal Radio is the only online dealer that I have seen that is currently accepting orders for the new Remtronix REM-820S antenna. Their $22.95 price for the REM-820S is only $1 more than they charge for the standard SMA/BNC Remtronix 800 MHz antennas (https://www.universal-radio.com/catalog/scanants/6119.html). If you need any other small items from Universal Radio (i.e. USB power adapters, etc.) it would make sense to order them at the same time to save on shipping as the flat rate $6.95 shipping charge covers any order up to $50.00. ($8.95 flat rate shipping charge for orders up to $100.00.)
If anybody comes across any other vendor(s) currently taking orders for this new antenna, please post the information here. Perhaps there will be a vendor(s) offering FREE shipping on this new antenna during the upcoming holiday shopping season.
I went ahead and bought from Universal Radio...............
I got this antenna yesterday and wow it works better than any antenna that I have used and the past.
It also works great on all bands. The bad part is 15 inches long. But the good part on 700-800 it has 11 DB gain. When I get the Remtronix REM-820S I will post how it performs also.
How do you know this to be true? Who is the manufacture, where are the specifications? The only thing I find claiming this is the ad on Ebay, yet even the Ebay seller's own web site does not make this claim. In fact they don't even make any mention of it at all.
Well I don't other than what you saw like me. The company is from Texas called Command Communications. You can contact them here. http://cmdcomm.com/contact/. or call 1-877-263-2666.
