I installed a J-Pole antenna from Snap-on Ferrite Beads in my attic recently and need some help to figure out why I am not able to get any signal out or hit local repeaters.
This is the setup:
I hooked up my Surecom SWR meter to the J-Pole antenna and it doesn't read anything. No SWR reading, no power reading, just 0's.
I also checked both jumpers for continuity with a multi-meter and they read 0 on both coax connector center pins and also on the external housing of the connectors.
I'm stumped as to what to check next. Is the 8W the Baofeng possibly just not a strong enough signal by the time it makes it to the antenna?
The only other things 2 things I can think of are the metal film on insulation panels on the inside of the roof and that the AC/heat furnace units are about 6 feet away from the antenna.
I'll still pretty new to building my on antenna setups so the answer may be obvious and I just don't know what it is. Any help or suggestions are appreciated.
This is the setup:
- Baofeng BF-F8HP handled w/ 8W
- KB9VBR 2-MeterJ-Pole antenna w/ N connector
- 3 Snap-on Ferrite Beads on the coax at the antenna (as recommended by KB9VBR)
- The antenna is mounted to a length of schedule 40 pipe and attached to the plywood with a mounting plate
- 3 hose clamps to secure the antenna to the pipe
- All 3 hose clamps are under the "T" section of the antenna
- Times Microwave LMR-400UF coax (40-45 feet run from the antenna to inside my shack)
- RFN-1006-3I N Connector at antenna
- RFI RFU-507-SI PL-259 at the end of the LMR-400UF cable
- RFI RFU-536 Female-to-Female PL-259 barrel connector
- LMR-400 jumper with PL-259 and SMA right angle connector to the Baofeng radio
- I also made a jumper with RG-58 with a PL-259 and SMA right angle connector to test with also
