I at times have +20 over line noise. Having a small yard and unable to put a K9AY rcve system in,trying the anc-4 with no luck at all.... I was bummed out until a voice said make your own rcve system..OK you believe that?? ,I do now! On 40,80,75,160 meters I tried listening on a 30 meter Double bazooka and the TH-11. Both were a big improvement but the TH-11 was far better and if i turned preamp #1 or #2 on & vaired the Attn.0N THE ICOM I could hear and work the FT5 & K4M with ease and on 160 meters and NO noise! ,where with out the TH-11 the Vert.loop was +20 over,no contact that way. However I needed just a little more gain at times and I pulled the DX eng RPA-1 Preamp out and connected it to the back of the Icom and wow total control of noise and Even with +25 over noise im hearning ft5 etc without noise !!! I have used the Rpa-1 on a on gnd rcve loop but it was just so so and not put in use again,but this TH-11 rcve on the low bands is a 10 !!!! just try it with the internal pramps first to see just what it does for you . If you need some more gain the RPA-1 is the finest preamp I have ever used it's as good or Better that the one in the Icom ,Excellent !! I hope this helps you as much as it has for me . Even with an S-5 NOISE LEVEL USING THE TH-11 for low band rcve there is no noise.Dont forget to rotate the TH-11,it makes a differance. G.L. 73 Dave KI0Z..

Great Performer

I agree with all the previous reviewers concerning this preamp..It is indeed excellent and performs as advertised...however...It needs an on/off switch to be truly useful in all applications..especially if powered from a station DC power pole or wall-wart application. Unplugging the power source gets tiresome.
It does require a slight bit of additional weatherproofing of the box if used outdoors also.

I just got this preamp, and it brought my Collins 75S-3B to life! It has virtually no noise of its own, and does a really nice jos around strong, overloading signals. I like the relay feature in the unit, which deenergizes when power is removed and the antenna is allowed to go straight through the preamp. This allows turning it off if desired, without losing the incoming signals. Well built and the documentation is professionally-written. This is one nice unit!

I have two of these running in a very demanding SO2R setup. The DNR is the best on the market. Noise figure is nice and low. Gain is adjustable if you need - change two resistor values. A really excellent desing and quality manufacture. The integral bypass relay is helpful as well.

Excelent Product

A very good pre-amp for my beverage antennas. Low noise and handles strong signals from local broadcast stations without a whisper of distortion.
I have several AM broadcast towers within line of sight of my QTH. The strongest by far is our local PBS station KUAT running 50KW during daytime hours. With no antenna on the receiver this station is s9+40-50 db. The RPA-1 handles my conditions with flying colors. I hear no spurious products at all coming from the pre-amp.
I will no doubt add more of these as my receive farm grows.
