The problem if the coaxial cable is used is the length it is.
The longer the cable in length the more signal leakage percentage goes up for the length of the copper cable that is used in the coaxial cable.
Also the more voltage is required to be passed down a cable or line that carries any sort of digital, or analogue signal transmitted down it.
If your intention was to connect to a Hub for cable TV and Internet services Gman.
where it converts fiber optic to copper cable signalling.
Apart from the cost of digging a ditch with adequate protective conduit laid for the coaxial cable to pass through and proper drainage, it will cost the cable company a lot of money to do for one cable laid down.
A copper cable can only be of a set length before it can no longer carry a strong enough signal down it and where the length of it requires more power down it to maintain the integrity or quality of the signal within the working frequency's or range it has to carry.
In other words the junction box, or hub where it is located 4th of a mile away for your line would require a higher voltage, and carry more signal loss to a point where the signal would be so weak that the cable modem ect could not lock to the frequency's or channels to get a good enough signal lock in most cases.
The cable company or cable engineer, of the Company should of explained this to you as to why they cannot run a coaxial cable a 4th of a mile from the street hub to your residence.
It`s not as simple as running a cable and expecting it to work.
The infrastructure required as said to get a cable signal to your house at the distance quoted would require signal boosters and higher voltage settings down the run length of the coaxial cable.
Money is not the point. it`s the physical limits and specifications of the cable you use.
If you look up cable length, and resistance over long runs of copper cable, and signal leakage per meter you will understand why sudden link cannot help you.
In order to get internet services and cable tv to your house a 4th of a mile away from the nearest street hub you would require the connection from it strait into your house to be Fibre optic.
And the cost of laying Fibre optic even at a 4th of a mile so you would get a good cable tv picture and a Internet connection that gave you a good speed ratio, without signal drop outs would cost sudden link to much money for one property a 4th of a mile away.
Unless you can get a fibre optic cable run for the 4th of a mile with a installation of fibre optic to the property.
You will practically be wasting your money trying to lay a coaxial cable of the length you require yourself,trying to get cable tv or internet services. Gman. The signal would be far too weak by the time it got to your property, Sudden link should know this.
It`s the physical caricaturists and limitations of coaxial cable that cause the problem, that prevent Sudden link from doing it. Let alone yourself Gman.
Have a read of what is bellow about capacitance of cable at long runs, the resistance, signal leakage and power required to maintain a frequency passed down a coaxial type cable.
The enemy is the length of the coaxial cable run.

Here is a rough reason if you read bellow why a 4th of a mile coaxial cable run will or might not work even if you installed it yourself Gman.
As the length of cable increases, it becomes more like a transmission line, and it becomes more important to make sure the impedance of cable is matched with the receiving end termination impedance. For shorter cables that have lengths that are less than about 1/10 of the wavelength of the carried signal, the transmission line characteristics don’t apply. In these cases, there is usually no need to match impedance levels, and the basic principles of circuit analysis can be employed instead.
For higher frequencies (RF), the wavelength decreases proportionally, and eventually, transmission line theory will have to be used in addition to circuit analysis. In these cases, it is also important to minimise reflections because they can result in standing waves, which can cause additional power losses and even dielectric breakdown for high power signals.
Transmission line theory is a very complex subject and as such is beyond the scope of this article. However, the essential lesson is simple: just match the source impedance with the cable impedance and also match this with the value of the receiving end’s impedance. This not only achieves minimum signal reflection, but in doing so it also maximises power transfer.
When using the transmission line concept, a coaxial cable can be represented as a series of capacitances and inductances. In this way, it behaves somewhat like a low-pass filter, where the cable passes most of the signal at lower frequencies and attenuates the signal at higher frequencies.
For frequencies above about 1MHz, the characteristic impedance of a coaxial cable line depends only on the dielectric constant of the inner insulator and the ratio of the diameter of the inner conductor to the inner diameter of the outer conductor (shield). Unlike the impedances for individual capacitors and inductors, the coaxial cable impedance is independent of cable length and frequency for frequencies above 1MHz. The impedance is about the same both for short and long cables, and for 2MHz and 20MHz signals.
