Hello K5TLF, try Altex Electronics in their blue bin isle for bulk RF connectors and Calrad RFcables.
For electronics in Austin it will be split between Fry's and the several remaining Radio Shack stores.
Or if your up for a small road trip, come down to Intertex Electronics, 1200 W Hildebrand SATX 78201.
We have been in business in San Antonio, Texas for 25 years and carry everything your post asked for.
Our website is
Home Page or you can call us toll free 1-800-820-3908 for info !
Hope this helps,
Michael-SATX
ps ~ Since the closure of the electronics store and ham stores in Austin, we have lots of tech industry,
UT Austin students ans teachers make the short trip down IH35S then slightly up IH-10W to see us.
We ship out twice a day via USPS and UPS Monday through Friday and were closed SAT and SUN.
If your looking for a very large selection of capacitors, resistors, transistors, diodes, IC's we have em !
Also, we carry MUCH more than on our website including Arduino and Raspberry Pi components, etc.
