Re: Warning, don't fry your modem.
So, I've done some more research on the HT2000W and its corresponding ODUs and found the following: -I assumed, since HN reps and installation documents routinely call the ODU a "radio" that all of the system modulation and demodulation was being performed outdoors. Apparently that's not the case, and HN is using incorrect terminology. -It appears that the system modulation is performed in the IDU according to its datasheet:https://www.hughes.com/sites/hughes.com/files/2017-04/HT2000_H56163_HR.pdf -Since the cable between the IDU and ODU is RG6, obviously Ka band RF (25+ GHz) is not travelling across that cable. The ODU is downconverting to some IF. Hughes won't tell us what that IF is.https://community.hughesnet.com/t5/Tech-Support/Need-to-know-IF-frequency-used-between-antenna-and-modem/td-p/82886 -Modern microwave systems often do have all of the RF components located in the ODU, yet still use coax to connect to the IDU, even though it's just digital data flowing between the two. Especially in residential satellite, installers are used to working with coax, and there would be additional costs and time associated with training them to work with outdoor twisted pair cabling. Also, coax conenctor ends are (in general) easier to waterproof than RJ series connectors are. So, bottom line, yes losses in the IF cable matter, but a slight impedance mismatch due to dielectric grease in a connector is not going to ruin the system margin. Here's the official doc from HN on IF cable lengths, which is telling:http://www.satelliteguys.us/xen/attachments/fsb_080202_01a_spaceway_cables-pdf.36329/5.1KViews2likes3CommentsRe: Warning, don't fry your modem.

Techs often overlook (or don't understand) how a dielectric grease will impact impedence in the connector. We rely on internal dielectrics in the cables to maintain a matched impedence and minimize signal loss and transmit power gain...yet we make it common place to impact impedences and increase the loss/gain while using a (sure its solid copper core) cable that has its own inherent signal loss issues regardless of impedence matching. It is truly a shameful practice in the RF world. If HN can't pinpoint problems with my system, I will be building an LMR400 cable from the dish to the modem, removing dielectrics, and changing all connectors to N-type and see what happens. Guarantee my speed will increase and transmit power will decrease. There are a lot of factors at play that should be customizable in these systems, but alas it is a cookie cutter product that is meant to work for Joe in the inner city with a 20 ft cable run, and Susie in the farmland with a 100 ft run. You are going to have a much bigger problem trying to use 50 ohm LMR400 in your 75 ohm HN system than you will with some dielectric grease in your F connectors. Also keep in mind that the cabling between the modem and the dish is not carrying RF. The radio in the system is located at the antenna feedhorn and is integrated with the LNB. Signal quality as measured by the HT2000W is determined at the dish itself.5.2KViews2likes6CommentsService going down periodically - beam 68
I have Gen5 service on beam 68 in Maryland. Last night, beginning at 10:09 PM EDT, I started getting notifications from my monitoring system that the Hughes service was down. This has continued throughout the day today. I logged in to the HT2000W and noticed that the receive signal strength is lower than usual- it's fluctuating from the low 50's to mid 80's. I usually have a received signal in the high 90s. I am not home now to tell whether there is an obstruction in front of the dish, but it's very unlikely that the dish has shifted--it's mounted using a very solid galvanized steel commercial antenna mount. Are there known issues on this beam right now, or am I looking at a local problem?Solved4KViews1like5CommentsRe: Configuring Hughes modem into an Office network
Bad news: this is impossible on Gen5 even if you're a business subscriber. IPv4 is delivered via carrier-grade NAT, so there is no way to set up inbound port forwards on your HT2000W. IPv6 public addresses are available, but they change very frequently so are equally useless. Please see: https://community.hughesnet.com/t5/Tech-Support/HT2000W-IPv6-inbound-services/m-p/83342#M58814 https://community.hughesnet.com/t5/Tech-Support/Remote-access-of-security-cameras-REVISITED/m-p/84688#M597286.7KViews0likes3CommentsRe: VLAN support on HT2000w Gen 5?
No VLAN support on the HT2000W. You'll need to configure your guest SSID to be on the same VLAN as your main network (the Unifi APs will isolate guests from the LAN through filtering in the AP if you enable that feature) or add a better router downstream of the HT2000W.3.2KViews0likes0Comments
