Whats the best cable to use John??
Hi Nidge,
The type of cable to use depends on various things:
1. What frequency your using.
2. Length of cable run.
If you are on the standard type 166Mhz (Base tx) and 172Mhz (mobile tx) then for a 100ft run of cable I would use Andrews LDF250. It costs a bit more but it will certainly make an improvement in your system.
If your running around 50ft then I would use Westflex 103 which is very good and not that exspensive.
On remote sites I use LDF450 cable which is a thick as your thumb.
I have always said that the majority of companies forget about their antenna system and radio dealers dont like to push this fact and just put up the first thing they can get.
I have put in four sites (voice and data) where they use the standard vertical antenna you normaly see and just below it a beam antenna to point in the direction that they are having the most problems with. Inbetween the two antennas I install a "Y" harness which allows both antennas to be connected to the one base station.
The vertical antenna gives you 360degree coverage whilst the beam gives you more gain on transmit and receive into trouble spots.
Other things that have to be considered is the do you need a remote radio site and if so what site, radio dealers in the past tend to put you on their own local site but that does not mean that its the best site for your operation.
There are 1000s of radio sites too choose from and the combined cost of site rental and BT landline (if required but there are ways of getting round this) is on average 4000 pounds per year which is not a lot if its going to give you the operational coverage you require.
Anyway, there is ALWAYS a solution. Its just a matter of people actually giving a damm and understanding what to do in order to resolve the issues.
regards
John
