'Random Wire Receiving Antennas' - Gen'l Question... |

Is it correct to 'generally' expect that for purely receiving voice (this question is not about transmitting) via a random wire for HF (AM or SSB) &/or VHF (FM) &/or UHF (FM) that I will receive more and clearer if I ALWAYS connect the antenna wire to a ground rod? Thx. - Fred. |
Q on dBi, dBd & dB(nothing) vendor data? |

When vendors (or even authors of some technical papers) report Antenna Gain with no relative reference to "i"-isotropic (dBi) or "d"-dipole (dBd), and therefore report the gain as simply a certain amount of dB, e.g., 3dB, should one assume that it means the same as dBi? I know that Antenna Gain is always a number that is relative to "something," and yet, as I have said, I see Antenna Gain from time to time reported with no reference to "i" or "d." Many thanks - Fred K4XXK. |
Drone aka UAV to put up stationary antenna? |

I have done a little time on the internet and found no experimentation, let alone commercial applications, of using drones (aka, Unmanned Aerial Vehicles aka UAVs) to position an antenna and 'sort of' hold it 'in place.' While realizing that this could take more drone heft to lift and hold any antenna that is technologically practical/feasible, I am still brazen enough to risk the embarrassment of posting herein / asking the question. Thanks (I am thinking I just might be hearing laughter in the background? :- ). |
