Re: GPS antenna splitter recommendation? (John Ackermann N8UR)
Usually a lurker here, but a couple of points. The best splitters are those designed for the task, such as the HP or symmetricom 4 way boxes seen from time to time on Ebay, though typically expensive. There are various issues: 1) The gps receiver will throw a fault if the antenna dc load is missing, though a simple fixed resistor load takes care of that. 2) The commercial units provide low noise gain to make up for the loss in a passive output splitter. 3) Typically, only one of the receiver ports is specified to provide the antenna power and also internal preamp power, with dc isolation for the rest. Can't see that a passive splitter would be an ideal solution without serious hackery, when you could build one using the cheap uhf amp gain block pcb's widely available now...
