Ideal for SDR users, it reduces overpowering AM signals to enhance reception quality, connects easily via SMA Female connectors, and is optimized for use with V3 dongles and direct sampling modes. ## Description Includes 1x RTL-SDR Blog Broadcast AM Reject Filter Designed to block the broadcast AM band between 500 kHz - 1.7 MHz with over 50 dB of attenuation. The 3 dB roll-off point is between 2.5 - 2.6 MHz. Works great with the direct sampling mode on our V3 dongles. This is a high pass filter and not a notch, so VLF will not work. Note, for RX use only. Note: Uses SMA Female connectors. Review: AM gone! - I was overwhelmed using my 41’ random wire at 25’ height horizontally installed between two trees with a 9:1 unun and 37’ counterpoise for my Raddy RF919 with a local AM radio station near me. I connected this at the end of my rg58 and the beginning of my rg316 that connects to the rf919. I did a scan and all those spurious signals are gone! It was really bad in the 2300-4000khz area. I’m very pleased. I seem to be receiving more signals now across the 2300-30000khz. It works as intended and the high rating is worthy. Solid construction and small in size great quality and Good price for all it has solved. Will buy another for sure. For shortwave enthusiasts, it’s a must have if AM is drowning you out. Review: Didn't help my 80m reception - Seems to do its job fine, but it is not a panacea for suddenly getting clean 80m ham band signals for me like others have reported. I cannot tell a difference on that band with it in place or removed on any ham band, using a Airspy HF+ Discovery SDR and a magnetic loop antenna. So this is not a silver bullet, and may not solve your interference issues. But it does attenuate the AM band as it claims to do. May be most beneficial to proper third harmonics of AM frequencies. Also with it in place it does attenuate the 160m band as it says in the title (2.6MHz HPF, 160m band is 1.8-2.0MHz). Would be better if it had a sharper rolloff closer to the edge of the AM band like 1.4MHz so that 160m could still be used. But, it does what it says it does, and is high quality and inexpensive, so 5 stars. ## Features - RTL-SDR Blog Broadcast AM Reject Filter - Blocks the broadcast AM band between 500 kHz - 1.7 MHz with over 50 dB of attenuation - The 3 dB roll-off point is between 2.5 - 2.6 MHz - Note: For RX use only - Uses SMA Female connectors. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N9SHS7P | | Best Sellers Rank | #90,261 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Radio Frequency Attenuators | | Brand Name | RTL-SDR Blog | | Customer Reviews | 4.5 4.5 out of 5 stars (192) | | Date First Available | January 16, 2017 | | Item Weight | 0.634 ounces | | Item model number | 4330366330 | | Package Dimensions | 4.06 x 2.64 x 0.67 inches | ## Product Details - **Antenna:** Radio - **Brand:** RTL-SDR Blog - **Compatible Devices:** Desktop, Laptop, Tablet - **Connectivity Technology:** Radio Frequency - **Connector Type:** SMA Female ## Images ![Broadcast AM Reject High Pass Filter (2.6 MHz HPF) by RTL-SDR Blog - Image 1](https://m.media-amazon.com/images/I/71JvOi90K-L.jpg) ## Questions & Answers **Q: Can this work with ham it up plus or would it i need it for ham it up plus? i want to pick up ulf and elf signals without am overloading things.** A: No. This is a high pass filter, which cuts signal levels by approximately 30db below about 2 MHz- including elf/ulf signals below 300 khz. You want a low-pass filter with a cutoff frequency below 500 khz. **Q: I just got this today and it does nothing for me:-( Is it directional? I have tried it both ways, with absolutly no difference at all:-(** A: If you're not having overload problems from a nearby AM transmitter, you won't notice any difference. It made all the difference in the world on mine, it was overloading so badly I couldn't use 80m or below. I don't think it matters which way you put it inline. If you have other problems, it won't help, it only works for AM band overload. **Q: Is this a series or parallel trap circuit?** A: Looks like a series trap. -C-C-C- | | | C C C | | | L L L | | | G G G **Q: Will this help with images from a.m. bcast I'm getting elsewhere, ie. 10-11 metres?** A: It should, it says high pass so it should cut off just below the 80m band. I have several local AM stations that were coming in on 80m and 40m, making 40m noisy and 80m unusable. This filter fixed both problems, it was night and day. If you're using a random wire antenna without a counterpoise you may still have some problems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ AM gone! *by C***R on May 17, 2026* I was overwhelmed using my 41’ random wire at 25’ height horizontally installed between two trees with a 9:1 unun and 37’ counterpoise for my Raddy RF919 with a local AM radio station near me.

This little device took care of that. Knocked the signal way down and cutoff most of the other AM stations. Small, Compact, easy to install and seems to be well built. I'm happy with the results on my SDR. ## Frequently Bought Together - Broadcast AM Reject High Pass Filter (2.6 MHz HPF) by RTL-SDR Blog - Broadcast FM Block Filter (88-108 MHz Block) by RTL-SDR Blog - RTL-SDR Blog Wideband Low Noise Amplifier Bias Tee Powered --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/44630462-broadcast-am-reject-high-pass-filter-2-6-mhz-hpf](https://www.desertcart.com.sa/products/44630462-broadcast-am-reject-high-pass-filter-2-6-mhz-hpf) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-10-21*
