                                                                                                                          VHF and UHF Installed

 

 

 

                                                                                                       First I try with Air core RF chock for HF

 

 

 

  

                                                                                 

Try with Diamond BU-50, no much difference

 

 

 

 

Antenna installed with out 40 meter

 

 

Antenna project 2010

 

 

 

have encounter some problem with my Antenna system

  • My Rig to the Antenna I have layed 225 feet cable for each Antenna, so the cable loss is high. I'm not able to receive weak signals and It's pickup lot of static noise.
  • My Antenna stack is too close so I unable to fix the TA-40-KR adapter for 40 meter.

My existing Antenna cable is Belden 9913F7 RG 8U and Times Microwave LMR-400 Ultra flex, so I looking further  very low loss cable, finally I decided to purchase Andrew Heliax LDF5-50A.

 

My rig to Antenna, I have to cross 17 bends due to the cable rooting.  LDF5-50A cable diameter over jacket is 1.08 inches. I was afraid, if I bend the cable  90 degree, inside contactor may change the shape, because it is a copper tube, then its lead to affect the impedance of the cable. I don't want to give up. I managed to get a special tool and try to bend a short length, after bend I open the cable and inspect it. The result is good. The photos are bellow.

                                                                                                                        After long bend

 

         

 

Outer jacket removed

 

 

       

Inner tube is in good shape

 

 

 

 

 

Top ends connected with Alpha Delta surge protectors

 

 

 

Another end of the cable, Rig side

 

 

 

 

Adapter connected

Antenna installation is completed

  • HF Antenna    : Mosley 6 band beam TA-63-N and TA-40-KR   ( 6, 10, 12, 15, 17, 20  and 40 Meter)
  • VHF Antenna : M square, 2MCP14 Circular Polarized Yagi.
  • UHF Antenna : M square, 436CP30 Circular Polarized Yagi.
