Isn’t the wavelength of 915 MHz 328mm?
I’m not sure how 400mm is half-wave?
Hi Peter,
Between the bracket, fittings and some elbow room, the total height is 400mm
Hi @Graham,
Do you have any extension cables for the 50ohm coax? I need a cable about 10m long to go between this antenna and my Laird Sentrius Gateway.
Thanks
Jon
Is it possible to replace the RG58 cable with something like the LMR-400?
Hi Graham.
Your blurb does say height without bracket 840mm.
While we are here how is 90cm shorter than 840mm???
Cheers Bob
Hi Peter. Yes, it is 328mm (without end effect adjustment)
It is for about 375MHz.
In all fairness it may be called a full wavelength vertical but we don’t know what goes on inside that fibreglass tube. To get a gain of almost 6db there are probably several 1/2 wave centre fed dipoles connected as a co-linear array. 4 would probably do it and would account for the 840mm length.
Cheers Bob
Thanks Rob, we’ll check out what went wrong with that description write-up!
Hey everyone,
The description on the product page has just been updated (you may need to clear your browsers cachet o show the update), I’ve double-checked the 90cm antenna we have in-house to make sure all the specs are okay and confirmed they are, so the 840mm antenna page has just had a slight edit made!
Thanks for notifying us Bob
