anyone knows where i can buy just the antenna mast and wire?
websites?

i have a spektrum module for my jr r-1 transmitter

I've bought replacement antennas from Dinball/RCMart via Ebay before. Took a couple weeks to get it from Hong Kong. Did a search and came up with this one from RCMushroom; supposed to be another reputable Hong Kong vendor but I've never purchased anything from them before:
