Yes, higher frequency signals lose power more rapidly in both cables and air. But, at this length, the difference between 2.4 and 5 is minimal.is there a difference between cable length on 2.4GHz and 5GHz networks? I've heard somewhere that 5GHz is more sensitive to that..
After quite some time I have to return to this question, so without dedicating a separate thread I'd like to ask again: what are the differences in quality between soldered or crimped N type connector tips. Crimped are obviously a lot easier to put on, but does that affect signal greatly? I'm asking because ever since I've soldered these tips with quite bad fortune and transition to crimping would save me lots of pain and concerns.. When a planned change of 10 cables is ahead, I don't really look forward to soldering 20 more connectors If I hear positive replies here, I'm going to buy connector pin crimping tool asapI now think that I'll replace all the N connectors with much more attention to quality, because some of them doesn't look so well.. So another question rises here, what N ends are the best, crimped, soldered or clamped..
Loss in the coax is
2.4 Ghz - 22.5db/100m
5.8 Ghz - 35.5db/100m
Cable loss is measured onto a dummy load on a test bench, and connectors have insertion loss quoted,A well made cable of that length should have a max loss of ~3.5 dB including connector losses.
We use Sektors with compartment to avoid cable. Operating 11n you getWell sorry, but you told nothing new here. We use integrated antennas absolutely everywhere except for AP. Can't say it's impossible, but hooking up an equipment container for each sector antenna on AP tower ain't very practical nor economic, is it? I'm not even talking about omni's or difficulty of maintenance.
Today I found some useful tips in Google about crimped or soldered connectors. Keywords are 'crimped vs soldered N connectors'. Imagine that..
Well if are going to use the "equipment container" and having several radio cards in that box, just imagine how the various RF TX signals will mix with each other and most importantly how they will effect the incoming RX signals from your client stations?, In other threads posters have advised against multiple radio cards onto just one board,....I'm thinking of a routerboard with 3-4 minipci slots, which I would place near the panels ....
Don't know where the equipment container comes into the setup when using Mikrotik gear after all most is very compact, and as STE replied =We use integrated antennas absolutely everywhere except for AP.

I would contest it is cheaper and very practicalbut hooking up an equipment container for each sector antenna on AP tower ain't very practical nor economic
There should be no maintence on a mast if the equipment has been properly installed and commissioned, Just regular visual checks that all is OK on site, unless you are referring to repair/adding or removing equipment off the mast, and with integrated panels it's much easier to work around cat5 than heavy duty RF cable such as LMR400 cable on the mast.Difficulty of maintence,
Do I gather than that there is no space on the mast remaining, what type of mast are you using can you attach a picture of your current layout from which suggestions could be forwarded, until then we are only guessing what to recommend if there is space restrictions,Using sectors with integrated containers are out of the question for me, because I simply have no means of placing them on my mast
No so as it’s totally dependent on usage of the radio cards used for instance following that rational the very popular Ubnt XR5 radio cards 3 should fit into a RB433AH but because of the size of the heatsinks, slots 1 and 3 can only be used ?I do believe that using adequate spaces between channels helps to avoid such problems. They wouldn't make RB's with miniPCIs spaced that near if there were serious problems, don't you think?
You are kidding?They wouldn't make RB's with miniPCIs spaced that near if there were serious problems, don't you think?

I've googled and come up with nothing.That's why on sites that have the dish up high, the unit has an up/down converter on the dish and the frequency going up the tower to the dish is a lot lower frequency (70 Mhz in our case). This reduces the loss at 5.8 Ghz to 1-2 db max.

S400 is the same as LMR400. It uses the same connectors and such.
Loss in the coax is
2.4 Ghz - 22.5db/100m
5.8 Ghz - 35.5db/100m
as you can see there is a 50% increase in loss between 2.4 and 5.8 Ghz. You also need to remember that this loss is bi-directional so you have the same loss on the transmit and receive sides. And if you are using the same coax on both ends now the loss is 100%.
For example using the numbers above, the difference over the total link (don't forget the 5.8 Ghz has a LOT more path loss than 2.4Ghz) Site A transmit loss is 13 DB, Site B receive loss is 13 db so the total increase in loss over the link is 26 db. That is the equivlent of doubling the length of the 2.4 Ghz run and then some.
That's why on sites that have the dish up high, the unit has an up/down converter on the dish and the frequency going up the tower to the dish is a lot lower frequency (70 Mhz in our case). This reduces the loss at 5.8 Ghz to 1-2 db max.
If I was running for any distance at 5.8 Ghz I would consider upgrading to LMR900 at the AP site.
