can I T off the T/Thunderbolt 10MHz feed to this board and take a second sine wave output direct from the Thunderbolt, to drive a transceiver GPS disciplined 10 MHz frequency standard input as well as having it feed the divider baord
The input impedance of the divider board is nominally 50 ohms (closer to 45 ohms, with 1Vrms drive from the TBolt). If the transceiver has a high-impedance input (1k ohm or higher), you should be able to get by with a simple "T" connection. Run coax from the TBolt to a BNC "T" at the transceiver input, and another coax from the "T" to the divider board. This will work best if this second piece of coax is short (i.e., the divider board and the transceiver are physically close to each other).
If the transceiver has a nominally 50 ohm input or the coax run between the transceiver and the divider board would be long, you should use a 50 ohm power splitter. Put the splitter close to the TBolt with a short run of coax, then run whatever lengths of coax are necessary from the outputs of the splitter to the divider board and the transceiver.
