New L-Band Patch Antenna Question

Post by WobbleOne » Tue Apr 13, 2021 3:24 pm

The new L-Band patch antenna being sold here specifies that it's max frequency is 1660 MHz. Would it also work well at the slightly higher frequency of 1680 Mz (weather balloon frequency with sufficient sensitivity?

If you head on over to the introduction page for this antenna you'll find the bandwidth plot towards the end of the page. 1770MHz looks possible, but already about 10dB down:

If the signal is strong then yes it will still see it, but as you're probably dealing with weak radiosonde signals it won't be the best choice.
