Which is good enough if you're just playing around on your desk but if you need range it probably won't work. Problem is that the HackRF is a really shitty receiver so it's a bad choice for weak signals anyway.Īnd the third reason to get a good antenna is transmitting, if you don't have a antenna with a good match most of the transmit power will just be lost to reflections. I got a simple passive one it works great down to ~3 MHz, to get lower i'd probably need a active one.Īnother reason for a good antenna would be if you want to receive very weak signals, in which case it can help to have a antenna perfect for the frequency range but it might not depends on the exact situation. If you go lower the wavelengths become really big so you need to buy/build something specialized like a mag loop. (but you could get lucky)ĭown to ~30ish MHz any long random wire will work just fine for receiving most signals. (For the latter case, a band reject filter would help.)Īnd, that antenna that works great for 1mhz is probably not going to be very good for 400mhz. If all you get is broadcast stations, either your antenna isn't big enough to pick up weaker stations, or the broadcast station is so loud that your radio can't hear anything else. The larger your antenna (even if it is less than 1/10 wl) the better it will work. Anything else needs to be stretched across a huge are, or will be so weak as to only pick up high power commercial broadcast stations, which the loopstick is actually quite good at anyway. The only thing that approaches that size and fits in your house is a loopstick style antenna (huge amounts of magnet wire wrapped around a ferrite rod).

In contrast, the Planar Disk is almost free and it performs quite well in an indoor setting.Īn effective (but poor) receive antenna needs to be at least 1/10 of a wavelength. Just because an antenna "is sold" does not mean its good or even marginal. Please verify your dongle is working with a good antenna before complaining that you cannot receive something. Here is a great, broadband Planar Disk Antenna that outperforms most commercial antennas of similar size for under $65-75 and can be built in a half hour or less by beginners with less than $10 in parts. See our wiki with tutorials and other resources including a Quick Start page to verify your dongle works.

"rtl-sdr" is a generic term for cheap USB digital TV (DVB-T) receivers that use the Realtek RTL2832U chipset, which can function as general purpose software defined radios (receive only).
