has anyone tried connecting 2 (or more) 800mhz yagi antennas together and then run them through a pre amp for better reception for receiving distant towers?
It can be done, but you need a phasing harness (coax) to connect them. This will allow a single feedline. Look at ARRL antenna handbooks for some guidance.
i could not get tv ch 11 so i used two antennas rg6 and a splitter in reverse (two antennas to one tv)
in receiving there are no rules just try anything.
