Yeah that is what I thought too. What good is an antenna pinned down on the grass and dirt? Answer was surprising to me come to find out. I acquired a SDR Receiver SRDPlay RSP2 FWIW to integrate and use as a Pan Adapter and play around with. Secondary reason is to listen to Commercial AM Broadcast, 160, and 80 meter bands. Even see if I can pick up NDB's. The RX has 3 Antenna Inputs to aid breaking up the broad spectrum of 100 KHz to 2 GHz to spread across 3 antenna systems. I started a thread asking for ideas on broadband antennas. Did not get much traffic in that thread, but I did get a couple emails about giving LoG (Loop On Ground) a try for frequencies 100KHZ to up around 15 MHz. Only requiring 60 feet of wire laid on the grass in a 15 x 15 square pattern is so simple, and I had the wire, I gave it a try. Mind you initially I did not measure things out or use any kind of Balun or Transformer, I just wired it in direct to the Hi-Z Antenna Input (1000 Ohm Balanced) terminals on the RX. At first I thought this LoG is not worth a flip, I lost 10 to 15 dbm of signal strength on the Spectrum Analyzer. Tuned in a distant AM Clear Channel Station about 100 miles away and it came in crystal clear with a SNR of 30 to 35 db. I could see stations I could not see using my 80/40/20/10/6 OCF Dipole. Not only could I see them, I could hear them pretty clearly with a SNR around 10 db. Encouraged, I went ahead and made a 9:1 transformer pill box to terminate the Loop to a 75 Ohm Coax ran inside to a 1:9 Transformer inside and terminated in the Hi-Z antenna port. Works better than my crude test model, so I am pleased. Yep I lost 10 to 15 dbm of signal level using my OCF Dipole up at 25 feet. However the Noise Floor fell from -100 to -95 dbm down to -140 to -135 dbm. So I traded 10 to 15 dbm of Signal loss, for a 15 to 20 db gain in SNR. Well worth the trade-off. There are a couple of downsides, and one of those may be a plus for DX'ers. The big downside is the LoG Antenna is restricted to the lower HF bands. Some say up to 15 MHz. Not so much IMO. I would say 10 MHZ for me at my qth. However on the lower frequencies from 400 KHz up to 40 meters is excellent. Example I could never hear WWV @ 2.5 MHz or Canadian 3.3 MHz time signal on the OCF Dipole. The other downside is it is not great at NVIS reception. It likes the ground waves coming in at low angles on the low frequencies which can be a plus for DX.
