more radio power, could compensate coax length?

Hi all.
We use WLM54AG-20 radio.
We tend to link the radio enclosure with antenna using a coax cable LMR400 for 1meter max to avoid too signal loss.
But sometime is not easy to install the radio so close to the antenna (maybe in summer yes, but in winter…).

What happen if I use a more powerful radio (i.e. WLM54AG-23) and 10 meters coax cable?

Is the same or there is something I dont know ?

Thanks

Merry xmas!

testing it would give u best answer

Increasing TX does not help with RX.

thanks RK, this is the answer.

Upsize to LMR600 if you wish to reduce cable loss.

6

better lmr900?

There’s not much redeeming good for LMR 900 as a general purpose cable. It doesn’t do 5.8. The connectors are very expensive and unfriendly.The cable is fairly expensive. So far all my needs have been met with LMR400, 600 and POE.

is the difficulty worth the extra cost in using lower loss cable lmr600 , lmr900 better work at having shorter cable even with the difficulty. only resort to that if it is imposible to use short cables

These are losses on 100m. And as RK already wrote, Increasing TX Power will not affect on Rx Sensitivity. I would suggest to use higher sensitivety ect SR-series by Ubiquiti, course price is much higher compared to compex cards.

Do you have to use on board radios?

Ubiquity has the Bullet5HP that eliminates coax loss by elminiating the coax.

No idea if this would work in your application
