What kind of antennas are you using? I just don’t get how in the world that could work with 900 and those numbers.
Longest stable shot with a 5700SM and reflector was 15.1 miles with clear line of sight. RSSI: 700, Jitter: 5-6, -80db. Link 95/90. Off of a 90 ft tower pointing at 115 ft tower.
Lot’s of fine tuning with the reflectror… :x
The integrated is 12dB.
Even with 12dB antennas at both ends, -86dB noise floor and 10dB margin you can get 40 miles.
ridnet, I was posting the readings on the radio. I assure you my HP service monitors are calibrated; however, these shown info was taken directly from the radio pages. I am sure that their results have some variability.
Allen,
I understand, But I’m talking about minimum free space loss.
The radio has an error of 4 dbm.
Calculations using 13 dbi antennas at 900 MHz.
Free Space Loss = 20 * Log10 (frequency in MHz) + 20 * Log10 (Distance in Miles) + 36.6
25.5 Miles
41.030 Kilometers
123.8 Free Space Loss
-----------------------------------------------
Signal Level = Tx Power- TX Cable Loss+ TX Antenna Gain - Free Space Loss + RX Antenna Gain - RX Cable Loss
Signal Level = 28 -0 +13dbi - 123.8 + 13dbi - 0
Signal Level = 69.8
-69.8 RX >>>>>>>>> Your radio 65/66
NOTICE: I have zero loss on cable and connectors.
I also used R&S Field And Strength calculator and it gave me -69dbm.
I also understand that you are getting your readings direct from the Canopy software. But, how can it have 4 db more ( -65dm )?
AH, are the antennas 13 dbi or 13dbd?
That would explain it.
The yagi antennas are the pac wireless 13 db yagi. I think they are rated at 13 dbi, but I have not paid that much attention to their spec. They were priced right compared to the y5900 I had been using.
This is a Moto 30/60 running very well. Take a look at the last line…
4ft dual pol antenna at 215ft and 2 - 2ft single pol at 240ft other end
Need to do an upgrade to get it up to 16.xx Mbps each way.

I have a 900 MHz SM on the same link that was working but shut off once we got the BH up and running. I’ll try and fire it up and get some stats to show. It is a 900MHz Conn SM with a yagi to an AP with a Horz Omni.

Re-regs get kinda high, but it was for testing purposes only anyways. Couldn’t believe this was from an Omni and a yagi. A cheap yagi at that.
I actually got a 1mbps download test speed to a local test site I use for testing.
:shock:
:shock: :shock: :shock: FROM AN OMNI :shock: :shock: :shock:
:shock:
AND IT’S ONLY 7dbd, 9dbi Antenna?
:shock:

So do you use a cyclone or did you just get this antenna?
Offtopic:
Why did you pick this omni vs MTI or PacWireless?
This particular one is a Cyclone, but found to piece it together was cheaper. But stuck with that antenna for the other 3 sites.

What size dishes?
most likely 28dBi pac wireless grids
twinkletoes wrote: most likely 28dBi pac wireless grids
Nope, the original ChannelMaster dishes that Mot sold as the reflectors.
Here’s another link, a pair of 5700BH 10s that has been in place almost 5 years. They originally had 3.1.5 code on them when we first set up the link. Also using the ChannelMaster dishes.
