Very informative and easy to understand. Thx for the demo.

[@survivalcomms]

You are welcome ! Thanks for watching !

Good info.

[@survivalcomms]

Thank you and thanks for watching !

I suppose the take away is,,keep the antenna feed line as short as possable. This video makes the point clear by putting the numbers on it. Thank you

[@survivalcomms]

RF feedline should be practically sized , as short as possible of quality construction with as few adapters / jumpers as possible. Thanks for watching !

Seem like less than 1.5 db/50 ft loss is not very significant. The higher the freq, the more loss? Anyway, its interesting. Great video

Thank you Timmo ! A 3db loss is cutting power in half so a 1.5db is equivalent to the loss of a quarter of the radio's power on transmit and loss of a quarter of the received signal strength. It isn't the end of the world and with a decent antenna it will be better than a wash in the balance of things. Loss does increase with increase in frequency but the compact nature (practical) of more efficient antennas at higher frequencies balances it out to a degree. Efficient antennas and feedline systems are a free (no additional power required) way to improve performance. Thanks for watching !
