Re: 700 MHZ DIY Double Biquad/Moxon Antennas


Never stop learning! Try and try again :)

I have had epic failures through the years and some very successful builds. Back about 18 years ago had a wifi company buy a design I made (was in a HAM magazine). Not talking big money, but sure felt good...

The biquads are excellent antennas. Friend of ...

Re: 700 MHZ DIY Double Biquad/Moxon Antennas


How is the element attached to the light shroud? You may be getting noise from the metal shroud reflecting at odd angles? The first one has a 20dbi increase, that's fantastic! Single band antennas do tend to have high gain.

You may also be getting crosstalk, try rotating them 90 degrees from each ...

Re: 700 MHZ DIY Double Biquad/Moxon Antennas

Played around with it a little last night and realized that I was getting a much worse signal on B25 but my download speeds were still a lot better. So next step, I'm going to build a B25 double biquad centered on 1900MHz to see how well it works. May even try a triple biquad... should be much ...

700 MHZ DIY Double Biquad/Moxon Antennas

Hi all, just wanted to share my DIY double biquad and Moxon antennas that I've been experimenting with. Would love to hear any comments or suggestions if you have any.

This started because I had some free time over the holidays and remembered someone on here experimenting with DIY antennas. I ...

Re: EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now

I think this is the only one they're offering on Facebook right now. 2x MIMO for 700-2700MHz because I'm on B12?

Re: EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now


I only see benefit from locking to single bands when the unit refuses to use bands that are of any use. Otherwise you could cause unnecessary issues.

Im partial to flat panel directional antennas. MIMO 2x and 4x are even better. Higher the gain the better. Absolutely shortest length cables and ...

Do I need to lock onto one band? What antennas do you recommend irregardless of wait times/customer service?

Got any recommendations? Amazon is usually my go-to but seems more like Alibaba when it comes to LTE equipment.

Re: EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now

Forum is acting fishy and didn't like my whole post so maybe if I split it up...

I've been scrambling because I need the internet for work. For backup, I've got my work cell tethered to another router.

I also have another set up ordered (see below) to see how well it'll work. Like I said, I'm ...

Re: EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now


Maybe I missed it, but are you locking onto one band?

I can help with finding antennas if you need

You have a good modem. Make sure your powering the enclosure with the aux power port as well, just in case your router isnt ouputting power very well.


I really appreciate the help! I haven't ...

Two things. You have a terrible amount of signal noise, the SINR stat, even though your RSSI and RSRP are in the middle of "meh, ok" range. Are you using a signal booster? Your original post showed a SINR of .2!!!! That is hot garbage. You have serious interference.

Second, Viper also pointed out ...

Re: EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now

Thanks!

That's what I was afraid of :(. I'm using CSpire which is a regional provider in the southeast US. It's just their regular hotspot plan. It disconnected around midnight last night so I assumed they were running some automated checks, and it saw something it didn't like.

EM7455, TPLink C7v2 - Worked for a day, won't connect to internet now

Hi, just wanted to start out by saying thanks for everyone that has put up all of the good information on this site. I live in a area where hotspots are my only internet option (except for satellite I guess), and the only hotspot that my carrier offers is a Franklin Wireless with no external antenna ...
