4K-compatible UHF/BS/CS booster, ideal for signal enhancement. - Brand: MASPRO - Model Name: UBCTRW30 - Function: UHF/BS/CS booster - Accessories: AC adapter, connection cable - Adjustment Features: BS/CS and UHF adjustment knobs Thank you for viewing. I purchased this to improve reception, but it became unnecessary as I took a different approach. I opened it and installed it once, but removed it immediately, so it hasn't been used regularly. However, there are minor scratches near the dial from the adjustment. I will include a gold-plated antenna cable (MASPRO, 1m). Please check the contents in the photos. Please understand the above points before purchasing. For shipping, I will wrap it in bubble wrap.
