[cma-l] Transmitter hosting for Community Radio Station

[Ian Hickling]

Agreed.As you know, we've submitted numerous proposals that use antenna gain and polar characteristics to increase power expressed in preferred directions and thereby reduce transmitter input power and feeder costs.
Coincidentally, we've just formulated a system to produce an aggregate ERP of 50W with a severe directional restriction requiring an input of only 8W.

 A good reminder Ian - it's amazing what you can sometimes get just for asking!


Another thing to bear in mind, especially if using higher powers, is that it can in the long run save you a lot of money to use a multiple antenna array for greater gain and lower power consumption. With the ever-rising cost of electricity, extra money spent on 2 or more dipoles can soon paid back by lower transmitter power (if you don't have to pay extra for the mast space of course).



Often it's also the case that capital money for setting up a project is less difficult to find than the day-in day-out running costs, so again spending more up front on a higher antenna gain can be a much more sustainable business case than finding the extra electricity cost forever more.

I've just had to do a rough estimate for a CR Licensee of electricity costs for his remote transmission site on a Local Authority.For a nominal 50W aggregate FM transmitter, processor, RDS encoder and link receiver we estimated a consumption of  100W at 240V single phase - 876kWh per annum - which at 15p/kWh gives £131,40 nett of VAT as a real cost per annum.In contrast - another Client has been told he is welcomed to locate his transmitter on roof of the the local Hospital - no fee - and no charge for power consumed.
So - if you ask the right people - it can be done!
