You MIGHT want to try an AMRAD antenna. I built one and it was fun. In fact, I built two; one for the house that works with 24 volts and another with a mag mount for my car on 12 volts (you have to use a different transistor). The AMRAD is an old design, basically a short whip used as an E-Field probe. Both of my whips are auto antennas bought at AutoZone. No tuning and no SWR to worry about. In fact, you can enlarge the built-in toroidal divider to become a multicoupler feeding as many receivers as you want. It is an active antenna, which means you have to build the board and house it in a piece of PVC with a heat sink, and you have to build a low-noise 24-volt power supply to handle about 100 ma. I use the classic CP-666 transistor, which is still available from Crystalonics. It's the single most expensive part. I think I spent a total of about $90 after I added a few "impulse shopping" things. Far Circuits in Dundee, IL makes, or used to make, the circuit boards for the active antenna and the power supply for a few bucks. Well worth it. E-mail them to see if they still have some. Basically, the AMRAD has a single transistor that serves not as a preamp but an impedance matcher, the same way car AM radios work, which is why they're so good. The CP-666 however has a much broader frequency range than AM radios but the same high dynamic range. I've never seen mine overloaded and the sensitivity is great from 150 kHz to about 25 MHz. Yes, E-field antennas pick up more noise than H-Field loops, but they're still just as sensitive and easy to hear signals in my personal experience. I'd compare my AMRAD's to any of my dipoles or my multiband vertical. Good to have the big-dog, the 24-volt version, on the roof with something like chicken wire under it for a counterpoise to keep local noise away. My car version works well with a mag mount, a strong one, and the lower power transistor does not need a heat sink. The home version needs about 6" of 5/8 copper tubing to radiate heat from the CP-666, and yes it does get hot. And yes, mine stays on 24/7. One of the LF groups recently used an AMRAD to re-create the first transatlantic contact. Some have said the AMRAD is great with the new software-defined receivers; for changing bands rapidly, good sensitivity, not having to worry about antena bandwidth, and just general operating convenience. I've never heard of one that works too well above 25 MHz, where preamps start to get important. The AMRAD is NOT a preamp ... it's an impedance matcher. At 1600 kHz a standard car radio with a standard antenna would see about 100 dB of signal loss if it did not perform impedance matching in the first stage. The AMRAD is great! The only problem is, you can't transmit out through it. I wish you could.
