What is the maximum usable speed of this transceiver over a run of a few feet? (A loopback test would be pretty easy to do if someone wants to try)

It would depend upon what transceiver it uses... you might try contacting the manufacturer. The spec is 10Mbps @ 40ft to 100Kbps @ 4000ft. The distributor's spec page indicates 300bps to 921600bps up to 1.2Km:http://www.serialstuff.com/usb-to-rs485-422-terminal-block/I have used this successfully under Windows 8 64-bit.

Its pretty good in terms of transmission. I checked on modscan to see whether my loop is transmitting the datas or not. It really helped me to find that on RS485 communication. Speed was not my concern but the data being transmitted or received was checked.

I had a 200' RG6 run. The voltage drop was within specs for the CM7777, which has a 30db gain vs the 16db gain for the CM7778 model. I am about 37 miles from the transmitting towers.FYI, my first CM7777 was DOA, the second crapped out within a week. If you open it up to look at the board, you are going to wonder what you shelled out 60 bucks for.

Yes, but buyer beware, I connected this as a repeater and it gave me barely usable speeds regardless of my range, I contacted Sabrent and the shipped me a replacement immediately (great customer service) but unfortunately the replacement unit yielded the same results.

No, USB will work at longer distances than 5m. I don't know the power rating, but receivers do not need a whole lot of power to receive a signal. I'm using mine about 2 blocks away and thru some trees and works flawlessly.

I tested it with my 200Mhz Arb. Gen.- At 10Vpp sine and square it seems to max out at ~33Mhz. - At 5Vpp it maxes out at ~23Mhz.- At 2.5Vpp it maxes out at ~13Mhz.My Arb. Gen. Maxes out at 10Vpp. The EX330 may go up to 40Mhz, but it is going to need a signal at more than 10Vpp so I'm not sure how useful this meter would be.

Sorry, don't know. My unit is off and stached away. I tried 2 different units, and it works as long as you don't move your computer. Move it by a couple of feet and latency increase and speed drops in spite of a full bar signal. I don't recommend it.

I have personally had the transmission device up to 15 feet away from the receiver with no detectable downgrade in quality. I have not tried any further than that.

lets think about this... 2000 meters is OVER A MILE!!!! Any claims like this should be ignored 100%. It may in fact do better than normal USB adapter but this "quoted distance" is bogus. Just like consumer two-way walkie talkies (they say 36 miles+) but that is under IDEAL conditions direct line of sight mountain top to mountain top.

Sorry, but I have not used it for a long run as a 1000 ft Try using a cat 6 instead.

You can safely go 700 feet between routers with this product without signal degradation. The "copper one" has a limit at about 400 feet or less.

You have to see what kind of signal they use. This one is 315mht. Look it up. Hope this helps

Ethernet is roughly 300' for a single run, it should work just fine up to that

From what I remember it's @30'. It's possible to extend it a short amount with high quality RG6 coax. You'll need TNC to F adapters & you must use the length of the supplied coax in order to maintain the 50 ohm impedance that the transceiver needs.

I receive good signal from 45 miles away, my height is 25 feet above ground and have some obstruction in the distance. I use a preamp and the signal is clear.

Using a RadioShack discone antenna 20ft up I easily transmitted 10-15 miles. With just the stock antenna probably five miles or so. Potentially hundreds of miles with the right conditions and antenna on 6 meters..

Yes, with digital transmission reception will be either great or non-existent. This could be due to cable loss if the run is too long and a line amp may be required. Just my two cents.

Past cable tech trainer for years. Signal loss over RG-6 over 100Ft is -6 dB @ 900 Mhz. Running 300' you are losing -18 dB. Might want to upgrade to RG-11 Less loss, nominally. -5.4 dB at 900 Mhz over 100'
