Review Summary For : Sotabeams bandpass filter for 2M
Reviews: 1MSRP: $46.98 USD
Description:
Designed and manufactured by SOTABEAMS, this neat bandpass filter is for use with handies (HT) in areas with multiple transmitters. In such areas, many HTs suffer from blocking. This is a ready-made unit - not a kit. Can be used either way round. Just connect between HT and antenna. Our filter is also perfect for use with SDR receivers which may suffer from blocking problems.
Product is in production

2.79 db insertion loss Time Owned: 0 to 3 months.
I purchased this filter to improve the transmit signal for the Ukraine 2M transverter. I should have paid more attention to the "3db in band attenuation". I realize it was designed to reduce 2M ht receiver overload, but you probably lose coverage with almost half your transmit signal lost in the filter. I suspect I might try this product: https://www.hobbypcb.com/index.php/products/uhf-vhf-radio/144mhz-band-pass-filter. Seems to have better insertion loss.
