[PPRAANet] Attic Antenna for 4W HT

[John Bloodgood]

You will want the majority of the run to be a lower loss, thicker coax. Examples might be 9913, RG8U, or LMR-400 coax.  You can do short flexible jumpers on the ends of smaller, more lossy coax like RG8X. You are still going to lose power, so keep the coax as short as possible.  If you are specifically hitting repeaters in one general direction, an antenna with some directivity/gain may help compensate for the losses. You have to remember that a J-Pole, 1/4 ground plane, Slim-Jim, vertical dipole, and most mag mounts all basically have the same performance: omni-directional with around 2 dBi of gain.

The extra height may or may not be worth it, the only way to know is to try.

Subject: [PPRAANet] Attic Antenna for 4W HT

Hello,

I am planning to buy an Arrow OSJ 146/440 j-pole antenna to mount inside my attic.  The length of the antenna should work in my attic.  My question is regarding the amount of coax cable to use.  The HT is a 4 watt unit and 50' of coax would be good to have available to move the antenna to different locations if necessary.  Will this length of cable work with my 4 watt HT and not cause too much loss?

Thanks.
Lee
