A comparison between ground connection of the coax shield and no ground connection. Field measurements of signal to noise ratios of the field station and the receiving station.
Hi, nice vids! I was wondering if you had any tests with ground on the transceiver and not on the ant. ground element on a balanced dipole coaxal feed? I have done better results with ground on the transceiver but with ground dependent systems, unlike a dipole which does not require a ground. though keep in note that your ground in this vid might of been with a higher flux on the results if you had added a 1.5l bottle of water to the ground at the ground rods. we must take into consideration the actual ground soil levels of conductance (moisture, rain, dryness of soil, etc.) to myself, out of experience the ground looks somewhat arid and poor for good ground conductance in your video. Most importantly, on a balanced system like a dipole ground is not much an issue, but a system using UNUNS like end-fed random wires such as a 9:1 unun or 4:1 system you will see great differences with the ground, unlike with end-fed half waves and 1;1BALUN fed dipole system. the subterrain type of soil, bedrock, etc. where antenna is placed also plays a great factor in antennas in the field , not surprisingly, is never the same value even in the same location during different seasons. lastly, on a non-ground dependent antenna system like a dipole, grounding the braid of the coaxial feed right after the 50Ω exit of the transceiver will result in signal degradation. Your choice of transceiver being a Russian made SDR holds superior technology in reception of signals and its extremely low voltage power requirement for both rx and tx to generate signal and rf is so advanced that its hard to tell with such a superior piece of kit, such kind of tests, unlike let's say a xeigu x-6100 or an ic-705 or even a FT-891(qrp levels) so take that into strong consideration as well. Nevertheless, awaiting your next vids. and results, 73s
hi love then content i have one too ptefere it to my 705 now ive looked everywhare for the screen protector with no luck could you provide a link for them please Dylan m0dsy
