I'd recommend a good grade RG-6 cable (70ohms) also. Regarding the
connectors, why not just use the standard TV F fittings all the way to the
Rx. You can put an F to whatever adapter on your Rx. TV cable and
fittings are not only cheap, but work quite well.

Agreed Ed.

I did see another post that suggested 50 ohms was better and to spend
the money.

The matched line loss of 150' of RG6 at 30MHz is 1.6dB. the MLL of
more expensive RG58C/U is 3.6dB, or the much more expensive RG213 is
1.6dB.

The antenna will not be matched over the whole range, so mismatch
losses will occur with both types of line, and there is no reason to
think that overall spending more money on RG213 with the attendent
loss of flexibility will actually be better.

In this rx only application, especially below 15MHz, even if the RG6
was a few dB worse than 50 ohm line, it would not be worth spending
the money on RG213.

Robert, if you want to bury the RG6, buy the standard grade and fit it
inside 13mm PE irrigation tube for better life.
