Wireless Joint

I'm using Tmobile data plan and Netgear m1 as a modem connected to AC1900P wifi router. I want to buy one additional modem for RV use because I learned that Tmobile band 71 helps signal reaches to extended ranges. But my mr1100 doesn't support b71.
But I still have some questions.
1. Does b71 worth the extra device investment when using in RV. Often time no signal at all.
2. MC7411 or EC25AF? I know one is cat 7 and another is cat 4. One support CA one doesn't. Does that just means one is faster? I don't really care the speed as long as it's enough for stream videos.
3. Does MC7411+NEXQ6GO work together?
4. Cudy LT500 or GL-X750V2? Both have EC25AF modem. x750 only have 2 internal antennas.I know gl.inet supports openwrt? how about cudy? which is more reliable?
5. Do they support ttl and imei repair?
6. Which antenna is recommended to mount on the RV roof? Am I supposed to use omni antennas, right?
7. Is there any other better options? cheaper or better signal

The MC7411 with the NEXQ6GO all day over the others. The MC7411 is "only" category 7 but it is based on a newer modem platform that is similar to the category 12 modems. (MDMx90 if I recall) I use the MC7411 in a lot of builds. It's been a great little modem.

If you want a little bump in router and get 5GHz wifi: https://thewirelesshaven.com/shop/route ... le-mc7411/

The NEXQ6GO will work with it, and you can upgrade it later down the line if you like, to category 12 or so. If you want a stronger base, the NEXS2GO would be better and you'll be ready for 5G modem support with gigabit ethernet if you'd like to future proof a bit. The NEXP1GO will also do this for you.

Omni antennas will do well if you are mobile and really don't want to have to aim your antennas, but this will always be at teh expense of power and capability that directional antennas offer.

All NEX routers have full modem command support and TTL/HL is included and simple to change in the routers WiFiX UI.

thank you so much for your reply. brought me a lot of advices. 5g or 2.4g is not a problem for me. both are more than enough for such a small camper.
what I really care is the size and LTE signal and perhaps a wide dc power range will be a plus as well.

size does matter. I wish it's portable size. maybe 1 wan 1 lan is enough. and no need to be five or six indoor antenna cuz outdoor antenna will be mounted for better signal.

actually I have several spare wifi routers still in the box, so I wish there is solely runs LTE modem with outdoor antenna only so I can connect it to wifi router I've already owned when better wifi performance is needed.

maybe something like this one gl-x300b but unfortunately it doesn't support band 71.

I think I found one. Netgear Lm1200 lte modem. Band Support : LTE CAT 4 (Up to 150Mbps DL and 50Mbps UL): B2/B4/B5/B12/B13/B14/ B66/B71
UMTS DC-HSPA+ (Up to 42Mbps): B2/B4/B5.
is this lm1200 using EC25-AF as well? anyone knows if the lm1200 can repair ttl and imei? thank you

update
I probably will go with LBR20
