What is the maximum length of cable that can be installed from the outdoor antenna to the booster? Also, are there any inline boosters that can be used with this system to increase the distance.

There's only one kit called WilsonPro 1050 that comes with an additional inline signal booster to compensate for up to 300 ft. of additional in-building cable signal loss.

Unfortunately, we cannot speculate accurately a max. specific cable length without knowing the strength of outside signal in decibels, and amount of sq. footage coverage you need inside.

The length of cable you can use without negating all benefit of signal caught by outside antenna will depend strictly on the strength of outside signal that exterior antenna can capture.

You can buy a cable as long as you need but it will incur signal loss at the rate of 4dB to 8dB per 100 ft. depending on the frequency.

Therefore, it is critical to use least length cable before it reaches amplifier which can then amplify it with up to +70 dB Gain.

A longer cable can be used much easily indoors from signal amplifier to interior antennas because boosted signal from amplifier can afford to incur signal loss caused by cable - but not as easily for cable run from outside antenna to amplifier.

If outside signal strength is not strong enough, the length of cable will negate all signal caught by exterior antenna, and your amplifier will not get anything it can amplify.

If you're using a length well over 75 ft., we recommend using LMR600 equivalent cables for about half the signal loss than LMR400 equiv. cables. 

If signal strength is good outside, and you're using this particular kit (Wilson Pro 70) for up to 15,000 sq. ft. inside, the maximum cable length we recommend for outside antenna is 100 ft. Please note that we include 75 ft. cable with this kit because that is enough in most circumstances and can justify the signal loss it incurs in most situations for mounting outside antenna pointed to nearest cell tower, as high as needed to catch max signals.

Sorry, if we have not answered your question fully, please contact us regarding your specific situation so we can help further.

Thank you.

Will this unit work with 5 G when it becomes available?

Great question - It covers 5G-E frequencies so called by AT&T Wireless but no, it will not cover all 5G frequencies. If full 5G coverage is needed, a 2nd booster (5G) will need to be installed to complement the system.

See details of upcoming 5G signal booster, the WilsonPro 710i which only covers 600 MHz 5G frequencies currently being used for T-Mobile, and US Cellular.

Please note that the 5G booster Wilson Pro 710i does not cover 4G frequencies so you will need both 4G & 5G boosters installed if you need 4G coverage too.

Please note that in many cases installing both 4G & 5G boosters may be redundant.

The reason is that when 5G coverage is unavailable inside a building, the cell devices like 5G cell phones and 5G mobile hotspots will automatically fall back to 4G network so 4G booster will do for most instances.

When 4G signal is strong enough thanks to 4G boosters, 4G provides fast-enough wireless data transfer speeds for all practical purposes on smartphones and mobile hotspots.

4G is here to stay because it "complements" 5G, 5G does not replace 4G as in the past when 4G replaced 3G.

4G is here to stay for atleast the next decade and beyond.

Therefore, you should be fine with a 4G phone, 4G mobile hotspot, and 4G booster for a very long time to come (10+ years).
