My Experiments With Antenna


Here is..rather was the 40mb dipole Horizontal centre feed coaxial antenna ...the snap was taken sometime before the partial dismantle of it for repair maintenance work etc...as its centre feed arrangement was not to my satisfactory...as no solderding was done...just wrapped the two wires with coax's parts..by black tapping only..though no apparent leakage of water etc...anyway this time I will try to improve this centre feed arrangement...soldering will be done at two ends connections with coax...two ends will be tips will be insulated with slight drop of feviquick adhesive liquid besides usual black tapping...etc etc...at centre feed...PVC pipe cuttings may be used....Let see..how far it goes...if after installation at the same direction as mentioned in the attached pix ..reception does not improve..may try it as Inverted V position or other orientation or ..wire materials will be changed to 1.5sg mm multi stranded  in place of present 2.5 sq mm ...let me experiments..--
I request you to send me your feed back at the location..of my antenna plus orientation...etc etc...both at the reception point & transmitting angle...Height 33ft approx. from the ground..orientation:North West to South East 
Polarisation:Horizontal..as mentioned earlier

My transreceiver is in the process of homebrewing by a fellow ham from Guwahati,VU3TQF.It may take a few more months to be ready as due to lock down some parts etc are not available.And I will also have to make arrangements for good quality coaxial cables etc for feedlines etc etc.I'm also in constant touch with  hams of our society i.e.Amateur Radio Society Of Assam(ARSA) based in Guwahati ..the capital city of our state Assam for technical expertise.I am also in ouch with other hams of India.

Meanwhile I'm monitoring the amateur bands by my Grundig Yatch Boy 80 with a long wire antenna of 78ft length and 30 ft length of .75 sq mm  multi stranded Copper wire with coaxial lead in.
More reports etc soon.
