You might want to try a dedicated receive-only antenna. I use a small loop, mounted on a pvc pole at ground level, located well away from my and neighbors' houses. The signal levels on the loop are less than with my wire antennas but so is the noise; sometimes (not always) the signal-to-noise ratio is noticeably better on the loop. I use a LZ1AQ preamp, mounted on the loop pole. If you check the LZ1AQ site you'll find lots of details. This preamp is quite robust & fairly cheap. There are a number of other receive loop systems available; some are pretty expensive. With a receive-only antenna you might need to use some T/R switching. My rig has a separate receive antenna port. Also, no RF protection is required with my arrangement (I checked the signal levels carefully on all bands while transmitting up to my maximum 100 watts output). So, it was pretty simple to set up.
