Co-Founder and Chairman of the Board at DISH Network
David, this is Charlie. Unfortunately, I'm not going to be able to answer a lot of what you asked other good questions for legal reasons when you have an offering in The Street. But let me just take a chance to maybe reset some things and then try to address what I can say about the questions that you asked. It was another really good quarter for us in terms of us doing a lot of things in a relatively short period of time. As we said last quarter, one of our goals was to stabilize the Retail Wireless business.
And while from an EBITDA perspective, we didn't do as well as we'd like to. We needed to stabilize that business, and we were successful in doing that and going from instead of losing over 100,000 subscribers each quarter to a very, very small gain, and that doesn't count the 139,000 customers we got from T-Mobile. So that was important for us to get our process in place to do that. We actually did have a bit unexpectedly with some growth in linear TV was certainly led by SLING, but one of the few companies in linear TV, maybe the only company that actually had growth.
Importantly, to a lot of people on this call, we had -- we continued to build our success to get with over 10,000 towers now constructed that can reach over 35% of the population. So we're still continued focus on that on the next milestone of 70%. And I think one thing that's not quite understood everybody is we're building 600 megahertz out. It includes all our frequencies when we're building these towers out. So we're pretty far down the path on 600 megahertz towards the final milestone of 75%, which only -- which affects the 600 megahertz milestone so I mean 600 megahertz frequency.
So that -- we continue to -- and we continue on that 1,000, approximately 1,000 tower pace per month. We're now poised for -- we are -- we've launched Boost Infinite internally, and we still have a lot of operational issues to make sure we're buttoned up on and you only get one chance to do it right for the consumer. But for our customers that we've launched internally, it's still a pretty good experience, but we've got some work to do. So that's going to want, but we're poised now to launch that in the first quarter, and we're launching that and John, maybe talk about this in a minute, but we're launching that on our own OSS/BSS system.
So today, we're on T-Mobile's system and so that's a misunderstood how important it is to get on to your own system there. And finally, we're in the market, to your question, we're in the market for funding today for the network. It's a $2 billion offering. And because that is limited to qualified investors, I can't go into details about that, but it obviously is funding for the network going forward. On the SPAC, I can't say a lot about that but the -- I think it would -- the SPAC did have high redemptions but is still intact and still a public company.
And still capable of doing -- nothing's really changed strategically there because in the SPAC world today, you're going to have to have a pipe and no matter what you do, you're going to have to other secured funding. So it may be a different set of shareholders. But there's still opportunity. One of those opportunities that's public is that there have been preliminary discussions with DISH. Let me take this back cat off and talk about DISH. Obviously, one of the things we've talked about is we like each sector of our business to be a self-funding as it possibly can be.
DBS obviously has been self-funding in the marketplace for Network to move in that direction. And we think that Retail Wireless is a unique position to do that as well as we enter the more of postpaid business because it doesn't have any debt, it doesn't have any capex and it's got 8 million subscribers. So it's a pretty interesting business and one that's got a lot of growth ahead of it. So I know I didn't answer everything that you wanted, but that maybe gives you kind of a reset of big picture.
