+1 I am sure you can use a lower loss cable. Are you using RG6 now or RG11?
At 1 GHz RG 6 6.1 dB loss per 100’. RG 11 has 6.6 dB loss. Switch to LMR600 and cut the loss in half. Yes there will be a slight impedance mismatch but not that bad.

THEN just find another 75ohm coax that will work with the same or less signal loss at 700ft...The fiber thing sounds like a disaster.

There is power and indoor space at the dish location, and there is already fiber run back to the house with multiple spare strands. 'People' I've talked to, say this is too far for a coax run. Searching online, it looks like there are some fiber options. Dish network branded or a company called 'Dawnco', but the equipment is about the same price in the $6000+ range for a 4lnb setup. Anyone come across a cheaper way to do it? 80 year old-Non-technical users, so need to maintain the DISH STB, no fancy streaming solutions. The dish today is about 250' away from the house on coax, and it will drop out in the slightest rain because of the signal loss over the coax.
