*Now down to two HF antennas at new QTH at Crosslands Retirement Community (Kennett Square) SW of Philly*

*
*

*Still have major high noise level from 1-10 MHz? and? working to solve it.
*

*
*

*1)? NVIS? horizontal? end-fed? 135 ft? -? tunes up easily on low end of 80m/40m/20m/ 17m/15m/10m*

*???? SWR about 2.5:1? on 30m band, but I have a Hustler mobile antenna for 10 MHz band
*

*2)? Vertical (made from old Cushcraft A10)? 16 ft? with home-made matching coil at base: covers 20/17/15 meters for low-angle DX with a few radials
*

*Both antennas doing well, catching signals from all over the world on the vertical.*

*Horizontal wire is doing well on the NBEMS regional nets on 80m and 40m.*

Hi Barry,
Did you tried to place chokes at the transceiver side and one at the feedpoint side ? That would normally solve your noise level issue.

Because noise is pickup by the braid of your coax.
